Question

Write the equation of the line that passes through the points (4,5) and (4,-6).

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

Answer 1

x=4

Explanation:

First find the slope

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

= ( -6-5)/(4-4)

= -11/0

This means the slope is undefined

Then means it is a vertical line

Vertical lines are in the form

x = constant

The constant in this case is the x value of the points

x=4
