Part a: what is the approximate y-intercept of the line of best fit and what does it represent? (5 points) part b: write the equation for the line of best fit in slope-intercept form and use it to predict the number of games that could be won after 13 months of practice. show your work and include the points used to calculate the slope. (5 points)

A. The approximate y intercept appears to be about 1.8 (slightly less than 2). What this tells us is that someone with 0 months of practice could expect to win around 1.8 games.

B. Using slope intercept form and assuming that the y intercept is at (0, 1.8), the equation can be solved for by finding the slope first and then putting the slope and the y intercept into the equation.

Slope (m):
points (0, 1.8) and (1, 3.0)
(Y2-y1)/(x2-x1)=(3.0-1.8)/(1-0)=1.2/1=1.2

Equation:
Y=mx+b
Y=1.2x+1.8
