You can put this solution on YOUR website! The slope is 0, so we already know our line is going to be horizontal. We know this because 0 is essentially . Knowing rise over run, this means we won't rise, we'll only run.
Slope-intercept form is y=mx+b. 0*x is 0, so there is no x. We only need to know b.
b is our y-intercept. In the points you have, the two y points are 10. So b=10.
Our answer is:
y=10
