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?
Answer/Solution
1
Steps/Work
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 = 1
The answer is E.
The slope of a line through (0,-2) and (4,2) is (2-(-2))/(4-0) = 4/4 = 1
The answer is E.
