Question

Find the slope of the line through each pair of points (20,-16),(19-16)

Answer 1

Answer:

Undefined slope.

Step-by-step explanation:

The formula should be y2 - y1 over x2 - x1

Points ( 20,-16 ) and ( 19, -16 )

So ( -16 - ( -16 ) ) over ( 19 - 20 )

0 over -1

The slope is 0. Undefined.

Answer 2

Answer:

Slope = 0

This line is not sloped. It moves flat relative to the x axis.

Step-by-step explanation:

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

= (-16 - (-16)) / (19 - 20)

= (-16 + 16) / (-1)

= 0 / -1

= 0
