Question

What is the slope of the line that passes through the points (7,-9) and (15, -29)?

Write your answer in simplest form.

Answer 1

-2.5

I got -2.5 as slope because slope is equal to rise over run so that means

the equation would turn out as -29+9/15-7=-20/8

-20/8=-2 4/8,-2 1/2,1/2=0.5,so the answer turns into -2.5

Answer 2

the answer is actually -5/2
