Best ResponseYou've already chosen the best response.1ahemmm... check the picture, or your book, on the slopeintercept form since that's what y=1/6x1 is in

Best ResponseYou've already chosen the best response.1The slope of line AB is given since the line AB is given. You can find the answer to which @jdoe0001 seeks by comparing your line y=1/6*x1 to y=m*x+b. y=m*x+b is called slopeintercept form because it tells you the slope m and the yintercept b.

Best ResponseYou've already chosen the best response.1not entirely sure what you are answering just now but I was asking for the slope of y=1/6*x1 notice this is in slopeintercept form it tells you the slope and the yintercept all you have to do is compare y=1/6*x1 to y=m*x+b can you identify the slope m (compare the two lines) ?

Best ResponseYou've already chosen the best response.1y=1/6*x1 upon comparing this to y=m*x+b you should see m=1/6 the slope of line AB (y=1/6*x1) is 1/6  now to find the slope of the perpendicular line just solve the following \[\text{ Solve the following for } m_1 \text{ which I'm going to call the slope } \\ \text{ of the perpendicular line } \\ m \cdot m_1=1 \\ \text{ where we found } m=\frac{1}{6} \\ \frac{1}{6} \cdot m_1=1 \]  one you have found that your perpendicular line in pointslope form will be: \[yy_1=m_1(xx_1) \\ \text{ where you are given } (x_1,y_1) \text{ as } (4,3)\]

Best ResponseYou've already chosen the best response.1you want to isolate m_1 try multiplying both sides by what it is being divided by try multiplying both sides by 6

Best ResponseYou've already chosen the best response.0yeah I was trying to figure what m1 was so i could multiply by 1/6

Best ResponseYou've already chosen the best response.1instead of solving that equation you could also ask yourself what is the opposite reciprocal of 1/6

freckles

Best ResponseYou've already chosen the best response.1opposite means: The opposite of a is a The opposite of a is a. You just take the number and change the sign to find the opposite. reciprocal means (if it exists) : The reciprocal of a is 1/a. The reciprocal of 1/a is a. You just take the number and flip it. So if I say find the opposite reciprocal of 1/6, this means you will change sign and also flip.

Best ResponseYou've already chosen the best response.1I know you can find the opposite reciprocal of 1/6... Just change the sign and then flip.

Best ResponseYou've already chosen the best response.1Changing the sign... it is negative, make it positive 1/6 now flip it, 6/1 or also known as 6. The slope of the perpendicular line is 6. You could have also solved that equation I gave. \[\frac{1}{6} m_1=1 \\ \text{ multiply both sides by 6 } \\ (6) \frac{1}{6} m_1=(6)(1) \\ \text{ notice } \frac{6}{6}=1 \\ ( \cancel{6})\frac{1}{\cancel{6}}m _1=(6)(1) \\ \text{ also recall } ()()=+ \\ +m_1=+(6)(1) \\ \text{ so we have } m_1=6\]

freckles

Best ResponseYou've already chosen the best response.1no I don't know where you got that from but 4/3*6 isn't 1 isn't 24/3 which is 8

Best ResponseYou've already chosen the best response.0where did you get those numbers from

freckles

Best ResponseYou've already chosen the best response.1I think you are looking for what I typed above where I gave you the point slope form of the perpendicular line which was: \[yy_1=m_1(xx_1) \\ \text{ where you are given } (x_1,y_1) \text{ as } (4,3)\]

Best ResponseYou've already chosen the best response.0the question I posted says to use those numbers Write and equation of a line perpendicular to line AB in slopeintercept form that contains point(4,3)

Best ResponseYou've already chosen the best response.1once you enter in the numbers above like you found m_1 and you are given x_1 and y_1 you can write in slopeintercept form which is y=slope*x+(yintercept) y=m_1*x+b

freckles

Best ResponseYou've already chosen the best response.1you found m_1 to be 6 replace m_1 with 6 you are given x_1 as 4 replace x_1 with 4 you are given y_1 as 3 replace y_1 with 3

Best ResponseYou've already chosen the best response.1I will give the equation in pointslope form one more time \[yy_1=m_1(xx_1) \]

freckles

Best ResponseYou've already chosen the best response.1distribute and add 3 on both sides

anonymous

Best ResponseYou've already chosen the best response.0@freckles answer is 42 correct

freckles

Best ResponseYou've already chosen the best response.1no y3=6(x+4) is a line you cannot go from a line to just a numerical value like 42 slopeintercept is of the form y=mx+b just use distributive property on 6(x+4) then add the 3 on both sides

freckles

Best ResponseYou've already chosen the best response.1do you know the distribute property? if you have a(b+c) then distributive property says this is a*b+a*c

freckles

Best ResponseYou've already chosen the best response.1so if you have 6(x+4) then what does distributive property say about this?

anonymous

Best ResponseYou've already chosen the best response.0I thought I knew what it meant so is it 6*x+4*x @freckles

freckles

Best ResponseYou've already chosen the best response.16(x+4) by distributive property we can rewrite this as 6*x+6*4 or 6x+24 so you have y3=6(x+4) y3=6x+24 now add 3 on both sides y=6x+24+3 y=6x+27

freckles

Best ResponseYou've already chosen the best response.1this is of the form y=mx+b which we call slopeintercept form

freckles

Best ResponseYou've already chosen the best response.1y=6x+27 is a line that is perpendicular to y=1/6x1 and also goes through the point (4,3)
