Answer:
-3
Step-by-step explanation:
y = -3x + b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
y = -3x - 16
This should be the right answer

Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32
