Answer: y= -1/2x - 2.5
Explanation:
Slope: y= mx+ b
m being the slope
b being the y intercept
You're given the slope, so you substitute m for -1/2
y=mx+b
y = -1/2x + b
You have the coordinates (5, -5) which you can substitute (the line passes through that point.)
-5 = -1/2(5) + b
-5 = -2.5 + b
+2.5 +2.5
-2.5= b
y= -1/2x + 2.5
Check:
-5 = -1/2(5) - 2.5
-5 = -2.5 - 2.5
-5 = -5
