Question

Which of the following lines is parallel to x = 7?

3y = 7
y = 7
x = y
x = 4

Answer 1

I got it, it was x=4 for those of you on FLVS

Answer 2

this is easy :)
find the parallel line

Answer 3

by checking the gradient you will know the answer

Answer 4

x = "a real number" is a vertical line through that number on the x-axis.

All lines below are parallel. They are all vertical lines.
x = 7
x = 4
x = pi
x = -2
x = pi
x = -pi/(sqrt(2))

since they all follow the pattern
x = "a real number"
