OpenStudy (imstuck):

Actually, A with the answer of 3 is incorrect.

OpenStudy (volleyballlover55):

oh really? so then what is it?

OpenStudy (imstuck):

Where x is 0, where NO miles have been traveled to charge for, is the rate that the company charges when you simply get into the cab to use the service.

OpenStudy (imstuck):

So when x = 0, the base cost is $8. If you were to put this into a linear equation, you would get y = 3x + 8. 8 is the y-intercept, where the values begin. They begin at 8 and grow from there. Swear.

OpenStudy (imstuck):

The rate of change is 3, but that's the slope of the line, not the y-intercept.

OpenStudy (volleyballlover55):

ok.....

OpenStudy (imstuck):

I think you're confused.

OpenStudy (imstuck):

I literally just taught this to a summer school class full of 9th graders last week. I'm a math teacher, I know what I'm talking about. I swear it's 8

OpenStudy (imstuck):

When you get into the cab, you will owe him $8, no matter what. For every mile he drives you, you add $3. So you can use your equation to tell how much he would charge you for any x number of miles you use his services. If you needed him to take you 10 miles, you would use your equation and fill in 10 for x to find out the cost would be y = 3(10)+8 y= $38

OpenStudy (volleyballlover55):

ok....

OpenStudy (volleyballlover55):

theres no option for 38 miles
