Question

I WILL MARK BRAINS!!! 10 POINTS

Write an equation of a line with undefined slope that passes through the point (-3,5).

A) x = 5
B) y = 5
C) x = -3
D) y = -3

Answer 1

C

A line with undefined slope is a vertical line parallel to the y-axis, passing through all points with the same x-coordinate.

For this reason it's equation is x = c

where c is the value of the x-coordinate the line passes through

For (- 3, 5 ) the x-coordinate is - 3, hence

x = - 3 → is the equation of the line
