Match each type of slope with the correct pair of points.
Zero slope
(-5, -20), (-11, -20)
Positive slope
(16,3), (16, -80)
Undefined slope
(-1000, 2500), (500, 4000)
w
(0, 4.25), (1.25, 1.75)
Negative slope

Step-by-step explanation:

(-5,-20) (-11, -20) Since there y value is the same, the line will be horizontal, making it have a zero slope.

(16,3) (16,-80) Since it has the points have the same x value, this is an undefined slope.

(-1000, 2500) (500, 4000) Positive slope, because as the x value increases, so does the y.

(0, 4.25) (1.25, 1.75) Negative slope, because as the x value increases the y value decreases.
