thede on the supermatt Higel paid $10 for 2 pounds of roast beef. The cost of del meal is proportional to its weight. What is the equation for the graph of this proportional relationship? (port)

Answer 1

Let "x" represent the weight of the roast beef in pounds and "y" represent the cost of the meal in dollars.

According to the problem, the cost of the meal is proportional to its weight. Therefore, we can write the equation in the form of y = kx, where k is the constant of proportionality.

From the given information, we know that when x = 2, y = 10. Let's substitute these values into the equation:

10 = k * 2

To find the value of k, we can solve for it by dividing both sides of the equation by 2:

k = 10 / 2
k = 5

Thus, the equation for the graph of this proportional relationship is:

y = 5x
