Question

Which of the following lines is parallel to x = 4?

Select one:
a. 3y = 9
b. y = 4
c. x = 2
d. x = y

Answer right and I'll love you forever!!!

Answer 1

It would be x=2 because the line x=4 would go on 4 on the x-axis and 2 would go on 2 on the
x-axis

It sounds confusing but look at picture

Answer 2

we know that

The line $x=4$ is parallel to the y-axis and is perpendicular to the x-axis

therefore

The line $x=2$ is parallel to the line $x=4$ , because is parallel to the y-axis and is perpendicular to the x-axis too

using a graphing tool

see the attached figure

the answer is

$x=2$
