Question 7 • TX-Algebra I A-CR

What is the equation of the line that is parallel to the line x = –2 and passes through the point (–5, 4)?

Answer
A
x = –5
B
x = 4
C
y = –5
D
y = 4

Explanation

The line x = –2 is vertical, so any line parallel to it is also vertical and has the form x = a. Passing through (–5, 4) means every point on the line has x-coordinate –5, so the equation is x = –5, choice A.
