x+y =15

x-y = 3

add the two equations

2x = 18

divide by 2

x = 9

x + y = 15

9 + y =15

subtract 9

y = 9

The two numbers are 6 and 9

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 equ
bogdanovich [222]
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
