Graph the line with slope -3 passing through the point (1,3)

A slope of -3 can be written as a fraction of -3 over 1.
In terms of rise over run, that means when we subtract 3 from y we add 1 to x.

So plot (1, 3), then go down 3 and over 1 and plot that point.
Make a line between them and you're done.

21.00 per mile and plus 5.50 is 26.50 i think that im pretty sure it is right
