Question

Consider the two functions described below.

Answer 1

Answer:

B. Compare the change in y over the change in x for each function.

Step-by-step explanation:

Find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

Change in y\Change in x

$\frac{200}{5} = 40$

y = 40x

By the definition of slope, you have your answer.

Answer 2

Answer:

The correct option is B) Compare the change in y over the change in x for each function.

Step-by-step explanation:

Consider the provided information.

We need to determine the correct description how to compare the rates of change in each scenario.

The rate of change of a function is: $\frac{Rise}{Run}$

Or the rate of change of a function is change in y over the change in x.

$\frac{y_2-y_1}{x_2-x_1}$

To compare the rates of change we need to compare the change in y over the change in x for each function.

Hence, the correct option is B) Compare the change in y over the change in x for each function.
