y = mx+b
draw the points on a graph. x-int is (-1,0) y-int is (0,1) you notice that you go up 1 and over 1 to get from the x-int to the y-int, in the positive direction of the x-axis and the y-axis. 1/1=1, so your m=1. b is the y-int, and that is given to you...1. so the whole equation is y = 1x+1 or just y = x+1.
