Since we want slope intercept form, we need to find the slop and the intercept. The y-intercept is given, (0,1), so b = 1. The slope is calculated using the slope formula (y2-y1)/(x2-x1): m = (0-1)/(-2-0) = -1/-2 = 1/2 so the final equation is y = x/2+1
Or you can use point slope form y-y1 = m(x-x1) y-1 = (1/2)(x-0) y-1 = x/2 y = x/2+1
