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 correct. If not what is the correct equation? Explain the answer. Consider the graph of the equation in the response.
No the answer or the expression y=6+x is not correct as it is a linear relationship.
The correct expression should be y= 6x where 6 is the proportionality constant and x is a independent variable on the dependent variable y.
