Question

What is the slope of(-4,5) to (-12,8)

Answer 1

rise/run
y2-y1/x2-x1
Answer: -13/17
(the whole fraction is negative not just 13)

Answer 2

-3/8

Explanation:

I would use a table

x y

-4 5

-12 8

from -4 to -12 you subtract -8

from 5 to 8 you add 3

so y/x = 3/-8

The slope is -
`(3)/(8)`
