Watch the video on “graphing two-variable inequalities” and answer:

  • a) To draw the first point of the line, what value of x is chosen?
  • b) At that first point, what values of y will satisfy the inequality?
  • c) What is the slope? Why?
  • d) What value of x is the “y intercept”? why?
  • e) Why the line is a “dotted line” (- – – – – – -) ?
  • f) If the inequality is ≤ we draw a “solid line”. Why do you think we do that?
