Simple interest earned graphed shows a curve, while a linear function is a line.

Answer 1

"Simple interest earned is the same each year much like the slope of a linear function is always the same."

Explanation: With simple interest, the amount increases by the same fixed amount each period (A = P + Prt), so the graph of amount vs. time is a straight line with constant slope (Pr).
