Question

The slope of line LM is 0.2. Point L is located at L(9, 7). Which of the following could be the coordinates of point M?

A. (2, 3)
B. (4, 6)
C. (4, 7)
D. (7, 9)

Answer 1

Let the coordinates of M be (x, y). Then
slope = (y2 - y1)/(x2 - x1)
(y - 7)/(x - 9) = 0.2
(6 - 7)/(4 - 9) = -1/-5 = 0.2
x = 4, y = 6

Therefore, the coordinate of M is (4, 6)
