Question

Function A is represented by the equation y = 2x+5.
Function B is a linear function that goes through the points shown in the
table.
X 1 3 4 6
y -1 3 5 9
Which statement correctly compares the rates of change of the two
functions?

A. The rate of change of function A is 5.
The rate of change of function B is 4.

B. The rate of change of function A is 2.
The rate of change of function B is 2.

C. The rate of change of function A is 2.
The rate of change of function B is 4.

D. The rate of change of function A is 5.
The rate of change of function B is 2.

Answer 1

Answer:

B

Step-by-step explanation:

rate of function A: 2 (coefficient for x)

rate of function B: 2, because an increment of 1 in x (e.g. 3 to 4) yields increment of 2 in y (3 to 5)
