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 (14,4). What is the slope of line m?
Choose the correct choice from the following answers:
A) -2
B) -1
C) 0
D) 1
E) 2
The midpoint of (2,8) and (14,4) is (8,6).   The slope of a line through (0,-2) and (8,6) is (6-(-2))/(8-0) = 8/8=
