Answer:
The slope of the line is m=0.26 and y-intercept is 67.6.
Explanation:
Given : Line of best fit :

To find : The slope and intercept in this context?
Solution :
The slope form of the line is

where, m is the slope of the line and b is the y-intercept.
Line of best fit is

On comparing with slope form,
m=0.26 and y-intercept is 67.6
Therefore, The slope of the line is m=0.26 and y-intercept is 67.6.
