Question

Please i need help as soon as possible

Answer 1

Let's take two points:

(0, 19000) and (4.5, 8000)

So we have:

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

Let's sub both points

(19000 - 8000) = m.(0 - 4.5)

11000 = -4,5m

m = 11000/-4,5

m = -11000/(9/2)

m = -22000/9

So,

(y - yo) = -22000/9 .(x - xo)

Put a point:

(y - 19000) = -22000/9.(x - 0)

y - 19000 = -22000x/9

y = -22000x/9 + 19000
