Question

Write an equation of a line that is parallel to the line y = 3x + 10

A) 2y = 6x + 8
B) y = 1/3x + 8
C) y = 6x +7
D) 2y = 2x + 10

Answer 1

Answer- A

Reason- in order to have two lines be parallel they must have the same slope, in this case the slope has to be 3x. If you look at A it is 2y=6x+8 and to graph it, y has to be by itself. so you divide both sides by two making it y=3x+4, and as you can see it now has a slope of 3x.
