Question

Which answer best explains the relationship between simple interest and a linear function?(1 point)

When calculating simple interest, the value can change during different years much like a linear function can have many different points.

Simple interest earned is the same each year much like a linear function has a graph that is curved.

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

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

Answer 1

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

Reason: With simple interest you earn a fixed dollar amount each period (I = Prt), so the accumulation vs. time is a straight line whose slope (interest per year) is constant.
