(y2 - y1) / (x2 - x1) ] using two points that are not data points.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

you would need to also lose 1 point for each of the other outcomes for it to be fair.
