Line m lies in the xy-plane. The y-intercept of line m is -2, and line m passes through the midpoint of the line segment whose endpoints are (2, 8) and (10,0). What is the slope of line m?
Choose the correct choice.
A) -1	B) 0	C) 1	D) 2	E) 3
The midpoint of (2,8) and (10,0) is (6,4).   The slope of a line through (0,-2) and (6,4) is (4-(-2))/(6-0) = 6/6=
