so the format of a basic equation is y=mx+b. M being the slope and B being the y intercept. Here the y intercept is 1 because that’s the point given. the slope equation is x2-x1/y2-y1. so i plugged the numbers in and got 2 and 1/2 for the slope. Just put that into the equation and you get y= 2 1/2x +1 Hope this helped!
