Mathematics 4 ESO – Unit 4 EQUATIONS AND INEQUALITIES Page 44 Activity 23
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?
