Answer:
y= 1/3x
Step-by-step explanation:
1.Plug the points into the slope formula- m=y2-y1/x2-x1.
So M=3-(-3)/9-(-9)
2.Solve: M=6/18
3.Simplify: M=1/3
4.Input into y=Mx+b
y=1/3x+b
The x and y won't be changed for this equation.
5.Plug in one of the points into the new equation
For (9,3): 3=1/3*9+b so B=0 because 1/3*9=3 which is what we want.
5.5 Or you can do it by solving for b: b=3-(1/3)(9)=0
6. Therefore B=0
7. So the end equation is y=1/3x
