## 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

## 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?
