Answer:
See below.
Step-by-step explanation:
Part A
Function A.
x y
3 3
5 7
6 9
slope = (9 - 7)/(6 - 5) = 2
y = 2x + b
3 = 2(3) + b
b = -3
y = 2x - 3
Function A is y = 2x - 3
Function B.
(0, 3)
(-5, 0)
slope = (0 - 3)/(-5 - 0) = -3/-5 = 3/5
b = 3
Function B is y = 3/5 x + 3
Function C is 3x + 1
Part B
The rate of change of a linear function is the slope.
Answer:
Function B
Function A
Function C
