Linear Quadratic Exponential Scatter Plot

A person travels by car.  They record their miles driven in a data table.  Calculate the linear regression equation of this data.

• y = 61.93x - 1.79

• y = -1.79x + 61.93

• y = 0.016x + 0.03

• y = 0.03x + 0.016

Find the quadratic equation for the relationship of the horizontal distance and the height of the ball.

• y= -18x² + 2.11x + 4.21

• y= -.06x² +1.06x + 7.9

• y= -6x² +1.06x + 79

• y= -.12x² + 2.11x + 4.22

Which of the following is the exponential regression equation for this data?

• Y = 8.16(2.7)^X

• Y = 81.6(2.7)^X
