Question

What is the equation in slope-intercept form of the line that passes through the points (- 16, 18) and (- 32, 30)

Answer 1

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

(30 - 18) = m.(-32 - (-16))

12 = m.(-32 + 16)

12 = m.(-2)

m = 12/-2

m = -6

(y - yo) = -6.(x - xo)

Now just choose a point

(y - 30) = -6.(x - (-32))

y - 30 = -6.(x + 32)

y - 30 = -6x - 6.32

y = -6x - 192 + 30

y = -6x - 162
