Step-by-step explanation:
his father's age= 4x
his mother's age= 4x- 7
his age= x
x+4x+4x-7=101
x+ 4x+ 4x= 101+ 7
9x= 108
=
x= 12

Step-by-step explanation:
Don’t mind the two parts I scribbled out, I didn’t a few extra steps when I misread the instructions. Just look at the top left corner and the right side of how I solve for the slope.
Answer:
y=-3x+2
Step-by-step explanation:

slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2
