Question

Find the slope of the line passing through the pair of points or state that the slope is undefined. Then indicate whether the line through the points rises, falls, is horizontal. or is vertical. (9, 2) and (9, -8) Select the correct choice below and fill in the answer box within your choice. A. The slope is (simplify your answer) B. The slope is undefined. Indicate whether the line through the points rises, falls, is horizontal, or is vertical. The line is vertical. The line rises from left to right. The line is horizontal. The line falls from left to right.

Explanation / Answer

Slope of a line is given by:

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

using the given coordinates

m = (2 - (-8))/(9 - 9) = 10/0 = not defined

The slope is undefined.

Since the slope of a line is not defined, which means it's a vertical line.
