what is the equation?

Answer:
y=-7/3x+17
Step-by-step explanation:
first find the gradient which is always the co-efficient of X .
gradient=3--4/3-6
3+4/3-6=7/-3
gradient=-7/3
use one of the pass points of the line and the other use an unknown eg (x,y) and the gradient to get the equation of the line.
(6,3) (x,y)=-7/3
3(y-3)=-7(x-6)
3y-9=-7x+42
the nine comes to the right side of the equation
3y=-7x+51/3
ans y=-7/3x+17
