Question

Find the slope of the line passing through the points (-8,2) AND (-8,-7)

Answer 1

the slope is undefined

Explanation:

(-8,2) and (-8,-7)

x1= -8

x2 = -8

y1=2

y2= -7

m=y2-y1/x2-x1

m= -7-2/-8-(-8)

m= -9/0 ,so the slope is undefined

Answer 2

undefined

Explanation:

In both point, y-coordinate are same. So, the line is parallel to y-axis.

The slope of the line parallel to y-axis is undefined.
