Answer:

  • Yes, the relationship is linear,
  • Constant rate of change is 0.5.

--------------------------

From the table we see a constant change in both columns:

  • For each $10 change in retail price column we see $5 change in sale price column.

It is the linear relationship and the constant rate of change is:

  • 5/10 = 0.5

Equation for this relationship is:

  • s = 0.5r, where s-sales price, r- retail price
