  • This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
  • y = mx + b
  • y = mx + b (–6) = (4)(–1) + b –6 = –4 + b –2 = b

  • so far is a value for is b (which gives me the y-intercept). Then all I need to do is plug in what they gave me for the slope and the x and y from this particular point, and then solve for b
