Question

Write the equation of the line that passes through the points (−7,5) and (-7,-8).

Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answer 1

x = -7

Explanation:

First we find the slope using

m = ( y2-y1)/(x2-x1)

= ( -8 - 5)/( -7 - -7)

= (-8-5)/(-7+7)

= -13/0

This means the slope is undefined and the line is vertical

Vertical lines are in the form

x= constant and the constant is the x value of the points

x = -7
