This graph goes through (0,3) and (2,5). You can pick any two points on the diagonal line.
Slope: m = (y2-y1)/(x2-x1) m = (5-3)/(2-0) m = 2/2 m = 1
The y intercept is b = 3 as the point (0,3) is on the line
Therefore, y = mx+b turns into y = 1x+3 which is the same as y = x+3
Note how plugging in something like x = 4 leads to y = x+3 y = 4+3 y = 7 and we can see on the given graph that (4,7) is a point on the diagonal line. So this helps confirm we have the proper answer
