This represents 1.75 per mile plus a one time 3 charge.
Another way this can be written is
(1.75m + 6) - 3
This is a less efficient way, but represents the same. It is 1.75 per mile, this is plus 6, therefore we add the -3 outside the parenthesis so it evens out to +3 as the base charge.
1. To find the slope, we need to have the equation in slope-intercept form, which is . In this case, our equation is already in this form. is what your slope is. In this case, our
2. To find the y-intercept we look at value that is in . In this case, is . So, our ordered pair is .
