Answer:
y=3x+3 is the function for this graph.
Step-by-step explanation:
Y=MX+B is the normal equation you would use for a graphed equation.
B is the Y intercept so you can add that. Y=MX+3
Now, you need to find the slope which is M. The equation to find slope is 
Now you need two points to fill in the Y's and the X's. (1,1) and (-1,-5) will do.


The you solve the fraction
m=3
