Types of Lines of Inequalities

Algebraic comparison

Compare the two following inequalities, then answer the question. y < x - 3 and What is the visual difference between the two inequalities above?

In the graph app C below, graph the following inequality y < x - 3

Graph app C

In the graph app D below, graph the following inequality

Graph app D

Compare and contrast

Compare the two graphs, A and B and answer the two questions. 1. What do you think causes the difference between dashed and solid line? 2. What do you think causes the difference between the shaded area?

Algebra work

Determine which inequality will be true for the point A=(2, -1). Use pen and paper to work out the problem. y < x - 3 or Describe below what did you do.

Plotting Point

Scroll up do Graph app C and Graph app D and plot point A=(2, -1) The point will lay on the line. Using your answer from Algebra work, what do you think it means if a point will be on dashed line compared to solid line?
