First you find the slope, which would be 8/-8, simplified into 1/-1. Than you just use one of the points to create point slope form. First you use the equation y=mx+b. Plug in a (0,3) maybe. So, that would be 3=1(0)+b. Simplify that and you have 3=b. Your equation is y=x+3

Answer:

y=-x+3

Step-by-step explanation:

This graph has a slope of -1. I found this by putting the rise (change in y) over the run (change in x) over any interval. From point x=0 to x=1 the function goes down 1 on the y-axis, so it has a rise of -1. Between the same two points, the function goes 1 to the right on the x-axis, so it has a run of 1. Put the rise over the run, and you get -1/1 or -1. This graph also has a y-intercept of 3. In other words, the graph crosses the y-axis at y=3. If you plug the slope (m) and the y-intercept (b) into the formula y=mx+b, you'll get y=-x+3.
