Answer:
y=x-3 (assuming your graph is counting by ones)
Step-by-step explanation:
Slope is 1, I chose two points.
0,-3 and 4,1
Then found the slope with those two points, which was 1.
Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.
So, I made my equation.
It took me awhile, but using the Rational Root Theorem and then synthetic division I got the first root. If you don't know the RRT you'll be in heaps of trouble doing this type of problem. I found the first root to be (x+6), then I did it again and got another root of (x+6) and the third one was (x-5). So the roots of this polynomial (and there are 3 because this is a 3rd degree polynomial) are (x+6) with a multiplicity of 2, and (x-5).
