Question

The equation of a line is y = mx + 2. What is the value of m (the slope) if the line passes through point A(−5, −18)?

Answer 1

We can input the point
remember that (x,y)
so we are given (-5,-18)
so when x=-5, y=-18
so

-18=-5m+2
minus 2 both sides
-20=-5m
divide both sides by -5
4=m
m=4
answer is 2nd option
