Are the graphs of the lines in the pair parallel? Explain.
zloy xaker [14]
Rewrite in slope-intercept form, y = mx + b, so that you can compare the slopes.

y = 4x + 6                              m = 4

- 15x + 3y = - 45
add 15x to each side
3y = 15x - 45
divide both sides by 3
y = 5x - 15                            m = 5

No, the slopes are different.
