Answer:
C
Step-by-step explanation:
Change in y over the change in x
-1-7=-8
1- -3=4
-8 divided by 4
Slope=-2
18
First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90
90x.20=18
Hope that helps
The equation in slope intercept form is y=-x-5
