Which of the following equations shows an initial value of 21 and is exponential growth?

• y=21(0.85)xy=21\left(0.85\right)^xy=21(0.85)x

• y=21(1.13)xy=21\left(1.13\right)^xy=21(1.13)x

• y=15(1.21)xy=15\left(1.21\right)^xy=15(1.21)x

• y=100(0.21)xy=100\left(0.21\right)^xy=100(0.21)x

Estimate the correlation coefficient for this scatterplot.

• A) r = 1.2

• B) r = 0.89

• C)r = 0

• D) r = -0.89

The linear regression equation for the data is  y = 1.5x + 12.  Interpret the slope of the equation.

• The slope is (0, 1.5).  It means that a pizza with 0 toppings will cost $1.50.

• The slope is 1.5.  It means that it costs $1.50 per topping.

• There are 1.5 toppings.

• There are 1.5 pizzas.
