Parallel lines have the same slope, First, you need to find the slope of the given line, then use that slope for the new line. To find the slope of the given line, solve x + 15 = 5y for y. Then put it in slopeintercept form, which is y = mx + b. m is the slope. Second, the equation of a line with slope m that passes through point (x1, y1) is y  y1 = m(x  x1) Try it, and ask for help if you need it.

Thanks,I need help putting x=15=5y into slope intercept form

First, switch the sides, so you start with 5y on the left side.

Next, the only thing happening to the y is that it is being multiplied by 5. How do you undo a multiplication?

\[x+15 = 5y\]Divide both sides by 5 to give\[\frac{x}{5} 3 = y\]Now switch the sides.

Umm I think that by dividing?? So will that mean that I'm dividing 15 by 5y??

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
Correct, divide both sides by 5

So then what will happen next to the x??

5y = x + 15 Divide 5y by 5 Divide x by 5 Divide 15 by 5

OK I got 53=y ..?..?..?

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.1
wait wait! I checked it and it actually its suppose to be y=1/53

5y/(5) = x/(5) + 15/(5) y = (1/5)x  3

Remember to include the x on the right side.

YESSSSSSS!!!!!

Since the original equation is now written in slopeintercept form, y = mx + b, you can read the slope directly. It's the number multiplying x, which is m. m = ?

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.1
m=4 so then that will mean that the final answer will be y=1/5x+4 xD

Where did you get a 4 from y = (1/5)x  3?

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
Remember, the slopeintercept form is y = mx + b, where m, the number multiplying x, is the slope.

What is m, the slope?
 one year ago

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.1
1/5
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
Correct. Now you know the given line has a slope of 1/5. The line that is parallel to it also has that slope becasue parallel lines have equal slopes. Now we start on the second part of this problem. What is the equation of the line that has slope 1/5 and passes through (0, 4)?

ineedyouubiebs Group TitleBest ResponseYou've already chosen the best response.1
4=1/5(0)+b which will then turn into 4=0+b
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
In the slopeintercept form of the equation of a line, y = mx + b, m = slope (you already know this) b = the yintercept Correct. b = 4, since the point you were given, (0, 4) is on the yaxis, so that is the yintercept.

Then I will do inverse operation and subtract 0 from both sides making it be 4=b
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
Now you know your new equation has m = 1/5 and b = 4. All you need to do is write y = mx + b and replace m with 1/5 and b with 4
 one year ago

mathstudent55 Group TitleBest ResponseYou've already chosen the best response.1
Correct, b = 4

and it will end up being y=1/5x+4
