Question

Which of the following lines is parallel to x = 8? (2 points) 3y = 16 x = 7 x = y y = 8

Answer 1

x = 7

Explanation:

The line x = 7 must be parallel to the line x = 8 so that we have an undefined slope. To check a line parallel to x = 8, It should start with x = some number having an undefined slope.

Answer 2

x = 7

Explanation:

The vertical line x = 8 has an undefined slope.

For the line to be parallel to another line, it has to have the same slope.

x = 7 also has an undefined slope, and it is a vertical line. Therefore, it is parallel to line x = 8.
