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
(2,9) and (-2,9)

Answer 1

Answer:

Slope = 0

Line = vertical

Explanation:

How to solve for slope:

Step 1. Use the slope-formula given the two points

Slope = change in y/change in x

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

Points: (2, 9) & (-2, 9)

Step 2. Plug in the points into the formula

Slope = (9 - 9)/(-2 - 2)

Step 3. Subtract

Slope = 0/-4

Step 4. Simplify

Slope = 0
—————————————————
The slope is 0 and since the points are on the same y-coordinate, the line is vertical

Answer 2

m= y2 - y1/ x2 - x1
m= 9-9/-2-2
m= 0/-4
m= 0

The slope is 0
