Find the equation of the line through the given pair of points. Solve it for y if possible.
-(9, 10), (9, -1)
A) x = 10
B) x = 9
C) y = 9
D) y = 10

Question

Quizplus · Accepted Answer

The line through the points (9, 10) and (9, -1) has a constant x-value, which means it is a vertical line. The equation for a vertical line is of the form x = k, where k is the constant x-value for all points on the line. Since both given points have an x-value of 9, the equation of the line is x = 9.
