Write an equation of the line described.
-Through (-4, 5), perpendicular to x = -2
A)y = 5
B)y = -5
C)y = -4x + 5
D)y = -4

Question

Quizplus · Accepted Answer

The line x = -2 is a vertical line. A line perpendicular to a vertical line is a horizontal line, which has an equation of the form y = k, where k is the y-coordinate of any point the line passes through. Since the line passes through (-4, 5), the equation is y = 5.
