What is the equation of the line that passes through (-2, 2) and (1, -4)?

(y - yo) = m.(x - xo)

Put both points:

(2 - (-4)) = m.(-2 - 1)

2 + 4 = m.(-3)

6 = -3m

m = 6/-3

m = -2

So -2 is the slope of this line

Now we have:

(y - yo) = -2.(x - xo)

Just put one point now.

y - (-4) = -2.(x - 1)

y + 4 = -2x + 2

y = -2x + 2 - 4

y = -2x - 2
