How do we find "m" and "b"? b is easy: just see where the line crosses the Y axis. b = 1 (value of y when x=0) Putting that into y = mx + b gets us: With that equation we can now ... ... choose any value for x and find the matching value for y. For example, when x is 1: y = 2×1 + 1 = 3. So when x=1 we have y=3.
