B undefined.
Slope = (y2 - y1) / (x2 - x1)
Slope = (8 - -9) / (-10 - -10)
Slope = 17 / 0
The line is vertical and therefore the slope is undefined.

The line is vertical and passes through -10, y where y has a number of values. Slope is infinite and B.undefined is the closest correct answer.

B
(8 - -9)/(-10 - -10) = 17/0

Connect the two points on a graph and see that the line is vertical so the slope is undefined, or -B-.

m = y2 - y1 / x2 - x1
x1 y1
-10 - 9
x2 y2
-10 8
