What's the question?

OpenStudy (anonymous):

reapeat, what is the question?

OpenStudy (anonymous):

Are the graphs of the lines in the pair parallel? Explain. y = 5x + 6 –18x + 3y = –54 A.No, since the slopes are different. B.Yes, since the slopes are the same and the y-intercepts are different. C.Yes, since the slopes are the same and the y-intercepts are the same. D.No, since the y-intercepts are different.

OpenStudy (anonymous):

if they are parallel then m1 = m2 = m3 etc

OpenStudy (anonymous):

Well, parallel lines have the same slope. So let's convert the second line to slope intercept form to see if they are the same. -18x + 3y = -54 Add -18x to both sides. 3y = 18x - 54 Divide each side by 3y. y = 6x - 18 6x is the slope of the second line. The first line has a slope of 5x. Are the slopes the same? Does 5x = 6x? No. So, the answer would be A.

OpenStudy (anonymous):

slope of y = 5x + 6 is 5 slope of -18x + 3y = -54 (reversed is 3y = 18x -54) is 18 So they dont have the same slope.

OpenStudy (anonymous):

nothing got to do ith y-intercepts

OpenStudy (anonymous):

got to do with coefficient of x

@BunnyBree says it right give her a medal

OpenStudy (anonymous):

Eh... id I not say nothing to o with y-intercepts?

OpenStudy (anonymous):

keep up there no @BunnyBree
