Answer:

-4

Option B is the correct option

Explanation:

Let the points be A and B

A ( -1 , 8 ) -----> ( x1 , y1 )

B ( 2 , -4 ) -----> ( x2 , y2 )

Now, let's find the slope of the line:


(y2 - y1)/(x2 - x1)

plug the values


= ( - 4 - 8)/(2 - ( - 1))

Calculate the difference


( - 12)/(2 - ( - 1))

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression


( - 12)/(2 + 1)

Add the numbers


= ( - 12)/(3)

Reduce the fraction with 3


= - 4

Hope this helps..

Best regards!!

Answer:

-4

Explanation:

In order to get from point -1, 8, to point 2, -4, you would have to go down 12 and right 3, which would be 12/-3, which would simplify to -4
