Question

Write an equation of a line that passes through (-3, 5) and (-7, 5).

Answer 1

y=5

Explanation:

First find the slope

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

= ( 5-5)/( -7 - -3)

= ( 5-5) / ( -7+3)

= 0/-4

The slope is 0

This means it is a horizontal line

Horizontal lines are in the form

y =

The y coordinate is 5

y=5
