Answer:
y = 120
Step-by-step explanation:
y = kx ur finding k
8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k
k = 8/3
Y = 8/3 45 now your finding Y when x is 45
Y = 120
to make sure do 120 = 8/3 45 should equal the same
I would think that it would be A.... I am an expert but, only in 8th, so I would double check.
