## 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?
