Reminder: y = mx + b, to isolate y, you would need to subtract mx value, and what you do to one side, you do to all. If there’s a coefficient in front of your y value, you then divide the equation by that coefficient. Once y is isolated, m and b values are easier to find.
Answer:
1) y = -2x + 1 // m = -2, b = 1
2) y = 5/8x - 1 // m = 5/8, b = -1
3) y = 7/8x - 3/4 // m = 7/8, b = -3/4
4) y = 3/4x + 4 // m = 3/4, b = 4
Answer:
a(b(5)) = 76
Step-by-step explanation:
Evaluate b(5) then substitute the value obtained into a(x)
b(5) = 5² = 25, then
a(25) = 3(25) + 1 = 75 + 1 = 76
