Question

Find the slope of the line passing through the points (9,-9) and (1,-1)

Answer 1

-1

Explanation:

To find slope, take the two points and find the RISE/RUN, which is y-y/x-x. Stay consistent with how you order the numbers. In this case, I'll do -1 -(-9) / 1 - 9. That will give you 8/-8, which when simplified gives you -1.

Answer 2

The slope is -1

Explanation:

Slope formula:

In (9,-9): 9 is x1 and -9 is y1

In (1,-1): 1 is x2 and -1 is y2

m= y2-y1/x2-x2

m= -1+9/1-9

Which is 8/-8

Simplify:

-1

The slope is -1
