Question

Suppose the relationship between x and y is proportional. When x is​ 29, y is 275.5. Find the constant of proportionality of y to x. Use the constant of proportionality to find x when y is 408.5. Use pencil and paper. Explain how you can tell a relationship that is proportional from a relationship that is not proportional.

Answer 2

If it’s proportional, then when X is 1, y is 2.6, you get that by dividing 275.5 by 29

so when y is 408.5, x is 156.91

I believe that is correct.
