STEP 1: Recall what is slope

STEP 2: Recall what is the slope-intercept form

STEP 3: Write the equation in slope-intercept form

No matter how many times you want to take books from the library, if you want to become a member, it will cost $40. This can be thought of as the y-intercept, or b value. After this, the total cost increases by $2 every month and this can be thought of as the slope. So plugging in m = 2 and

The equation for this situation is therefore y = 2x+ 40
