Answer:
(A) y = -2x + b
(B) y = 0.5x
(C) y = 2/3x - 28/3
(D) y = -2x - 11
Step-by-step explanation:
(A) 0 = 2 · -4 + b
b = 8
Equation: y = -2x + b
(B) 1/2 = 0.5
-1 = 0.5 · -2 + b
b = 0
Equation: y = 0.5x
(C) 2/3 stays the same
-6 = 2/3 · 3 + b
b = -28/3
Equation: y = 2/3x - 28/3
(D) -3 = -4 · -2 + b
b = -11
Equation: y = -2x - 11
