Answer:
(a, b, c, d) = (2, -3, -2, 2)
Step-by-step explanation:
The horizontal segment where y=3 extends from x = -2 to x = 2. These are the values of c and d, respectively.
The slope of the left piece is up 2 for over 1, so is 2/1 = 2, the value of a.
The slope of the right piece is down 3 for over 1, so is -3/1 = -3, the value of b.
So, we have ...
