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

Assuming the driver continues at the same speed, what distance will the car have traveled after 8 hours?

• 324 miles

• 513 miles

• 400 miles

• 494 miles
