You can put this solution on YOUR website!
Plug the ordered pair into the equation.
If it satisfies the equation, it is a solution.
If it doesn't, it's not.
y=3x%2B7
Try (2,11)
11=3%282%29%2B7
11=6%2B7
11=13
False, (2,11) is not a solution.

Try (-2,1)
y=3x%2B7
1=3%28-2%29%2B7
1=-6%2B7
1=1
True, (-2,1) is a solution.
