Question

Does anyone know the equation to this graph

Answer 1

Explanation:

let us take any two points on the line say (-3,-6) and (3,8)

`slope=(-8-(-6))/(3-(-3)) =(-8+6)/(3+3) =(-2)/(6) =(-1)/(3) \\eq.~of~line~is ~y+6=-(1)/(3) (x+3)\\3y+18=-x-3\\x+3y=-3-18\\or~x+3y=-21\\or 3y=-x-21\\or~y=-(1)/(3) x-7`

Answer 2

Y X
(1,3)
The y goes down once and x goes across 3 times
