  1. But what about this m, now we know the y and x are variables. If I plug in a
  2. value for x, I get a value for y. Just like for intercept if x is zero then y
  3. would be equal to three. So what about this m, what is this thing we've labeled
  4. m correspond to? Let's see, instead of looking at these graphs I'm going to look
  5. at two different graphs. Graphs that have different m's.. Here is the line y
  6. equals 2x plus 3, and this is the line y equals one half x plus three. So what's
  7. different between these two graphs? Is it the steepness? The y-ntercept or the b
  8. in the equation y equals mx plus b.
