y = 1.2x (option A)
Step-by-step explanation:
the relationship of the price of tomatoes to the weight is proportional one.
A proportional relationship is in the form of y = kx
where k = constant of proportionality
our k here, is the rate of change of tomato price to the weight.
we can pick any two points to find the change
Using points: (weight, price) = (0, 0) and (10, 12)
Rate of change = change in price/change in weight
Rate of change = (12 - 0)/(10-0)
= 12/10 = 1.2
We insert the value of k in to the formula:
y = 1.2 × x = 1.2x
The function that best represents the relationship in the graph: y = 1.2x (option A)
