Question

Which line is parallel to the line y = 3x + 6?

Question 1 options:

y = -3x – 6


y = 6x + 3


y = -1/3 x + 6


y = 3x – 9

Answer 1

y = 3x - 9, because for a line to be parallel it has to have the same gradient (x value) as the first line, and y = 3x - 9 is the only equation with the x value of 3.

Answer 2

Answer:

y = 3x - 9
