The graph is not available. However, for a proportional relationship that goes through the origin, the equation is of the form y = kx where k is the constant of proportionality. So if the price of footballs is represented by y and the quantity of footballs is represented by x, then the equation would be:
y = kx
where k is the constant of proportionality.
The price for footballs is displayed in the graph. Derive the equation of the proportional relationship through the origin.
