Question #22910

Answer 1

X =8 does not have a defined slope.

Explanation:

Slope is the change in y divided by the change in x

`(y_1 -y_2)/ (x_1- x_2)`

Take two points on the line ( 8, 2) , ( 8,0)

Put these points into the equation for slope.

`slope = ( 2-0)/(8-8)`

`(2-0)/(8-8) = 2/0`

Dividing by 0 is undefined.

X =8 has a slope that is undefined.
