Question

The line y = mx + 6 passes through the point ( 1, 3). find m.

Answer 1

m = - 3

Explanation:

since the line passes through (1, 3 ) then the coordinates of the point make the equation true.

substitute x = 1, y = 3 into the equation and solve for m

3 = m + 6 ( subtract 6 from both sides )

- 3 = m
