Answer:
Slope: 
Equation: 
Step-by-step explanation:
The line of the best fit passes through the points (0,8) and (4,6).
If the line passes through the points
and
then the slope of the line is

Hence, the slope of the line of the best fit is

The equation of the line is

where m is the slope and b is y-intercept, so the equation of the line of the best fit is
