given that y varies with x, write the linear function relating the two variables.
y=8 when x=72
.
When you see "y varies directly with x" think
y = kx
to find 'k' plug in the given values of x and y and solve for k:
8 = k(72)
8/72 =k
1/9 = k
.
Answer then is:
y = (1/9)x (this is what they're looking for)
