If the slope of the line is 1/2, each point will rise by 1 (along the y axis) every time it runs by 2 (along the x axis). Think of rise/run. The y-intercept is always at the input of 0, and since the output of the y-intercept isn’t given, it can start at 0. So put (0,0) for the first column. In the next column begin adding 1 (for y) and 2 (for x) in each column
