Answer:
y = 16x
Step-by-step explanation:
You want an equation for the proportional relationship described by the (x, y) pairs (1, 16), (2, 32), (3, 48).
A proportional relationship is described by the equation ...
y = kx
where 'k' is the constant of proportionality.
The value of k can be found as ...
k = y/x . . . . . . divide the above equation by x
For the first pair of values in the table, this is ...
k = 16/1 = 16
The equation for the relation is y = 16x.
