anyone?

OpenStudy (ash2326):

@Zephious we have \[y=mx+b\] y= monthly cost of the car, if you put x=0 then we'll get y=b Do you get this?

OpenStudy (anonymous):

a little lost sorry

OpenStudy (ash2326):

If you put x=0, what do you get?

OpenStudy (anonymous):

monthly cost =b?

OpenStudy (ash2326):

yeah so b represents the cost even if the car is stand still

OpenStudy (anonymous):

now assume that it costs 179.10 per month for insurance and car payments, and 45 cents per mile for gas etc ....

OpenStudy (ash2326):

then b=179.10 ( fixed cost per month) and m= 0.45 ( cost per mile)

OpenStudy (anonymous):

that was alot easier to figure out than i thought, algebra can be tricky lol

OpenStudy (ash2326):

You just have to try, it's easy:)

OpenStudy (anonymous):

Math to me is like the bubonic plague, lol
