Question

Sam wants to write an equation to represent a proportional relationship with a constant of proportionality of 6. He writes the equation y = 6 + x. Is he right

Answer 1

No, Sam is not correct. The graph of a proportional relationship has the form y = kx, where k is the constant of proportionality. Sam added the constant of proportionality instead of using it as the coefficient of x. The correct equation is y = 6x. Sams graph would’ve a straight line, but it would not pass through the origin.

(Just did this in edgenuity)

Answer 2

No, because the slop proportional relationship is y=mx+b. That means that he is missing something.
