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 (6, -4). What is the slope of line m?  Choose the correct option
A) -3
B) -1
C) -1/3
D) 0
E) 1
The midpoint of (2,8) and (6,-4) is (4,2).   The slope of a line through (0,-2) and (4,2) is (2-(-2))/(4-0) = 4/4=
