M 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 y-intercept represent?

the cost for each hour it takes to repair the machine
the service fee 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

The slope represents the cost for each hour it takes to repair because following the y=mx+b template for an equation m= slope and in this problem 45 is in that place and it is being multiplied to x which has been stated as the hours taken to repair. this shows that 45 is sort of a rate price for each hour. the answer is A.

Step-by-step explanation:

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

Step-by-step explanation:

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 what slope in this function represents.

The general equation of the line is given by

Where m=Slope of line

c=y- interceptComparing 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 the number of hours is multiplied by 45 then we get a total cost of x hours.

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