Question

The campsite you want charge a rent fee of $15 to reserve the site plus a extra $3 per day define your variables and write a linear equation in slope intercept form to represent the cost of the campsite

Answer 1

The equation would be y = 3x + 15.

Since there is a flat rate of 15, that is your y-intercept.  The $3 charge is variable and depends on the number of days, so that would represent your slope.
