What is the rate of change
Elza [17]

Answer:

The rate of change is 1

Step-by-step explanation:

In order to calculate the rate of change, take two points (in this example I'll use points (8, 2) and (10, 4)) and input them into this expression used to calculate rate of change: \frac{y2-y1}{x2-x1}

\frac{4-2}{10-8}

Solve:

4 - 2 = 2

10 - 8 = 2

2/2 = 1

The rate of change is 1.

Hope this helps :)

The cost of a service call to fix a washing machine can be expressed by the linear function y = 45 x + 35, where y represents th
Effectus [21]

Answer:

B. The service fee for coming to look at the machine

Step-by-step explanation:

Whenever we have a linear equation like this in real-world problems, the y-intercept always represents a fixed cost of some sort.

Here, 35 is the y-intercept. It cannot represent "the cost for each hour it takes to repair the machine" because that's what 45 means.

It cannot represent "the total cost for fixing the washing machine" because that's what y means.

And it cannot represent "the amount of time that it takes to arrive at the home to make the repairs" because that's what x means.

Thus, 35 must be the service fee. This is the upfront fee that is fixed and doesn't change depending on time.

Hope this helps!
