Question

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 the total cost and x represents the number of hours it takes to fix the machine. What does the slope represent? the cost for each hour it takes to repair the machine the cost for coming to look at the machine the total cost for fixing the washing machine the amount of time that it takes to arrive at the home to make the repairs

Answer 1

a

Explanation:

Answer 2

the slope represents the cost for each hour it takes to repair the machine.Step-by-step Answer:

We are given that the cost of a service call to fix a washing machine can be expressed by the linear function

Where

y=Total cost of a service to fix the machine.

x=Number of hours takes to fix the machine

We have to find that slope in this function what represents.

General equation of line is given by

Where m=Slope of line

c=y- intercept

Comparing the general equation with the given function

We get m=45,c=35

m=45 represents the cost for each hour it takes to repair the machine because when number of hours multiplied by 45 then we get total cost of x hours.

Hence, the slope represents the cost for each hour it takes to repair the machine.
