the pieces of michael's rope were (28 in)/5 = 5.6 in long.
the pieces of brenden's rope were (30 in)/6 = 5.0 in long.
michael's rope was cut into longer pieces.
the slope is found by using the formula
the points are (1,4) and (1,-3)
m = (y2-y1)/(x2-x1)
= (-3-4)/ (1-1)
= -7/ 0
when we divide by 0 the answer is undefined
