Answer:
1) The line is passing through the y-axis at -3.
  Now to find the slope, use . We'll use the points ⇒ (-2, 0), (0, -3).
   = Â
  The slope of the line is .
  Â
   Plug in what we know into y = mx + b.
   m is the slope and b is the y-intercept.
  Â
   y = -3/2x - 3 is the slope-intercept form for #1.
2) The line is passing through the y-axis at -1.
  Use the same slope formula, . We'll use the points ⇒ (1, 0), (0, -1).
   = Â
  The slope of the line is 1.
  Plug the numbers in to y = mx + b.
  Â
  y = x - 1 is the slope-intercept form for #2.
