Answer:
m = 2
Step-by-step explanation:
Given
y = mx + 2
Since (- 3, - 4) is a point on the line then it satisfies the equation.
Substitute x = - 3 and y = - 4, the coordinates of the point, into the equation and solve for m, that is
- 4 = - 3m + 2 ( subtract 2 from both sides )
- 6 = - 3m ( divide both sides by - 3 )
2 = m
