The linear regression equation is y = 61.93x - 1.79.  Identify the y-intercept of the equation.

• Y-Int = 61.93

• Y-Int = -1.79

• Y-Int = (0, -1.79)

• Y-Int = (0, 61.93)

The linear regression equation is y = 61.93x - 1.79.  Identify the slope of the equation.

• Slope = 61.93

• Slope = -1.79

• Slope = (0, -1.79)

• Slope = (0, 61.93)

The linear regression equation is y = 61.93x - 1.79.  According to the equation, the y-intercept can be interpreted as:

• After 0 hours of driving, they went -1.79 miles.

• They are driving -1.79 miles per hour.

• They drove 1.79 miles total.

• They drive 1.79 hours total.
