1)
C represents more of a linear model for the data because it has equal amount of points on both sides of the line.
2)
This equation is set up in y=mx+b
M is your slope and b is your y-intercept.
Your slope is -2. Y-intercept is 24.
y=-2x+24
3)
When J=2, the line his K at 20.
4)
This equation is set up in y=mx+b
M is your slope and b is your y-intercept.
Your slope is 15. Y-intercept is 40.
y=15x+40
