Firstly, you can use the slope and the first point to find a second point: 2 + 1 = x2 and 6 + 5 = y2 because the slope is 5/1. Next you can write the equation in point-slope form (remember point-slope form is y - y1 = m(x - x1): y - 11 = 5(x - 3) Another equation would be B because B is the correct equation if you choose 2 as x2 and 6 as y2. Hope this helps!
