Answer:
y=-
x-5
Explanation:
Start with the slope equation
.
This is the slope of your equation
Now rearrange the slope-intercept equation to get your y-intercept
y=mx+b
y-mx=b
Now substitute either of your two points to find your y-intercept
-10-(-
(8))=b
-10-(-5)=b
-10+5=b
b=-5
Now that you have slope and the y-intercept you can write your equation:
y=-
x-5
