Write an equation in pointslope form of the line through the given points. Then write the equation in slopeintercept form.
#11. (4,0), (2,1)
#12. (3,2), (5,3)
#13. (5,1), (3,4)
Thats all they give you.
And YES I do know the Formulas:
Pointslope: yy1=m(xx1)
Slopeintercept: y=mx+b
Slope: m=y2y1/x2x1

Best ResponseYou've already chosen the best response.0first.., find the slope using the third formula that you write.., then use pointslope formula to find the equation..

Best ResponseYou've already chosen the best response.0m=y2y1/x2x1 (4, 0) (2, 1) m=10/24 m=1/6 m=y2y1/x2x1 (3, 2), (5, 3) m=3(2)/5(3) m=5/8 m=y2y1/x2x1 (5, 1) (3, 4) m=41/3(5) m=3/8

Best ResponseYou've already chosen the best response.0@Butterfly16 Thats what I've done before, but then people come along, and tell me I'm wrong! ):

Best ResponseYou've already chosen the best response.0And why are you finding the slope 3 times?

Best ResponseYou've already chosen the best response.0because you have three questions and each question have equation... :)

Best ResponseYou've already chosen the best response.0yy1=m(xx1) (4,0), (2,1) y0=(1/6)(x4) y0= 0.16x+0.7 y=0.16x+0.7 Yeah, I just finding the slope for all of them. :o)

Best ResponseYou've already chosen the best response.0now.., using the similar way.., you can solve questions #12 and #13 can you? :)

Best ResponseYou've already chosen the best response.0y1 and x1 just stand for the points. So (4, 0) is the point, so y1 is 0 and x1 is 4. That would the equation for the pointslope form for that set of points.

Best ResponseYou've already chosen the best response.0but you have to write it in pointslope form?!

anonymous

Best ResponseYou've already chosen the best response.0Then, I guess you can just plug in the numbers into the pointslope form so it'd just be: y0=(1/6)(x4)

Best ResponseYou've already chosen the best response.0but don't you have to do 2 equations because of (4,0) and (2,1)

Best ResponseYou've already chosen the best response.0@Butterfly16 has write it in slopeintercept form slopeintercept form is y = mx+ c , No.., points (4,0) and (2,1) are on the same line.., so just choose one of them..

Best ResponseYou've already chosen the best response.0Yip, the line would look like that. :o)

Best ResponseYou've already chosen the best response.0#12. i got that far but I'm stuck now.

Best ResponseYou've already chosen the best response.0yy1=m(xx1) (3, 2) (5, 3) y(2)=(5/8)(x(3)) y+2=0.625x1.875 y=0.625x3.875

Best ResponseYou've already chosen the best response.0Yup, so for #12 it'd be y=0.625x3.875

Best ResponseYou've already chosen the best response.0but thats y=mxb it should be y=mx+b though right?

Best ResponseYou've already chosen the best response.0no, it depends, if you are adding a negative, its the same as subtracting, and its okay @MaeganR

Best ResponseYou've already chosen the best response.0how do you get from y1= 3/8 x5 to y=mx +b form?

Best ResponseYou've already chosen the best response.0idk. I was trying to do it like @Butterfly16 was doing it.

Best ResponseYou've already chosen the best response.0oh and its y1=3/8 x+5

anonymous

Best ResponseYou've already chosen the best response.0so you add 1 to 5 and you get..

anonymous

Best ResponseYou've already chosen the best response.0wasn't that easier than you thought?

Best ResponseYou've already chosen the best response.0Well, it seemed like the other people were kinda confusing..
