y = 1.33
Step-by-step explanation:
A proportional relationship is one relationship of the form:
H = k*X
Where H and X are variables, and k is the constant of proportionality.
if the graph passes through (12, 16), this means that when X = 12, H = 16
16 = k*12
Now we can find the value of k.
k = 16/12 = 1.33
Then we can find y knowing that x = 1.
H = 1.33*x = 1.33*1 = 1.33
then y = 1.33
