Write the equlf each line in slope intercept form slope is 3, and (1,5) is on the line

The answer is: y=3x+2

We are given with two conditions: week 5 having 45 dumpster loads removed and week 10, with 30 loads of dumpsters. we translate this into points (5,45) and (10,30). we find the slope between, we have 15/-5 or -3. we plug in to the equation y-y1 = m (x-x1) where m is the slope. y - 45 = -3 *(x-5). we simplify and get y-45 = -3x +15 or y +3x -60 = 0.
