To find the constant of proportionality, we can use the formula y = kx, where y is the cost of ice cream custard in dollars, x is the weight in ounces, and k is the constant of proportionality.
Given that the graph has two points (0,0) and (15,3), we can substitute these values into the equation:
0 = k * 0
3 = k * 15
Since the first equation gives us k * 0 = 0, we can ignore it. We can rewrite the second equation as:
3/15 = k
Simplifying this equation, we find:
k = 1/5
Therefore, the equation of the graph is y = (1/5)x.
At the Custard Creamery, the cost of ice cream custard is directly proportional to its weight in ounces. Complete the equation of the graph with its constant of proportionality. the graph is 0,0-15,3
