Yes just plug the numbers under x onto the equation and solve it to get y. For example, I take the 4 under the x section and substitute x in the equation, 3x + 1 for 4 which would look look like 3(4) + 1. Now to get y solve it. In this equation 3(4) + 1 would equal 13. For the (x, y) part substitute the numbers under x and put the number. then substitute y for the answer to the equation. It would look like this.
