Answer:
A. -0.875
Step-by-step explanation:
Find where the points are located
A=-4.25
B=2.5
Add the points
-4.25+2.5=-1.75
-1.75/2=-0.875
W = 1.414213562 (or 2 squared)
x = 2 (because the y gets cancelled out in the first equation)
y = 1 (since 2(1)=2(1))
tell me if i’m right :)

Let y= years ago when dad's age was 4 times son's age
60-y=4(30-y)
60-y=120-4y
-y+4y=120-60
3y=60
y=60/3
y= 20 years ago
Then 30-20= 10 yrs. old, the boys age when his dad was 40 years old.
