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, 4) and (6, -10). What is the slope of line m ?	Select the correct option:
A) -3
B) 1
C) -1/3
D) 0
E) Undefined
Ans: B   Solution: line m goes through midpoint of (2, 4) and (6, -10). midpoint is (4,-3)   as we can see that the y axis of intercept point is (0,-2) means line m is parallel to x axis   slope M= 1   Ans: 1
