Step-by-step explanation:
5x + 60y = 35
x +y = 1.5 : rewrite as x = 1.5-y and substitute this formula for x in the first one:
5(1.5-y) + 60y = 35
distribute:
7.5 - 5y + 60y = 35
combine like terms:
7.5 + 55y = 35
subtract 7.5 from both sides:
55y = 27.5
divide both sides by 55 to solve for y
y = 27.5 / 55 = 0.5
now substiute 0.5 for y in the 2nd equation:
x + 0.5 = 1.5
x = 1.5 - 0.5 = 1

Morgan is right because to find how much something is per minute you need to divide. In this case, you need to divide 68 and 8. The answer then is 8.5
Answer:
y - 9 = -6( x - 0)
y - 9 = -6x + 0
y = -6x + 9
