Answer:
y=6x+20
Step-by-step explanation:
m= y2-y1/x2-x1
m= -4-8/-4-(-2)= 12/-2= 6/1
y= mx+b
y= 6x+b
8= 6(-2)+b
8=-12+b
+12 +12
b= 20
yes
Applying a dilation centered at the origin with scale factor has the effect of multiplying both coordinates of a point by :
So, in your case, the coordinates of the points double:
-4x - 20x
Multiply 2 by -10
