Answer:
15
Step-by-step explanation:
To find the y intercept set x=0
You are given two points: (7,-6)(-4,27)
y=mx+b
y2-y1=x2-x1
x1=7
y1=-6
x2=-4
y2=27
27-(-6)/-4-7=27+6/-4-7=33/-11=-3
y=-3x+b
-6=-3(7)+b
-6=-21+b
+21 +21
b=15 so, y=-3x+15
PLUG IN O TO THAT EQUATION
y=-3(0)+15
Your y intercept would be 15
