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

Based on the table, use quadratic regression to determine which function can best be used to model this situation?

h(t) = 99t2 + 858

h(t) = -4.9t2 + 295t + 0.6

h(t) = -4.9t2 + 295t + 2

h(t) = 99t2 + 1,470.3
