Compare the two following inequalities, then answer the question. [br][br]y < x - 3[br]and[br][math]y\ge x-3[/math][br][br]What is the visual difference between the two inequalities above?
In the [b]graph app C[/b] below, graph the following inequality[br][br]y < x - 3[br][br]
In the [b]graph app D[/b] below, graph the following inequality[br][br][math]y\ge x-3[/math][br]
Compare the two graphs, A and B and answer the two questions. [br][br]1. What do you think causes the difference between dashed and solid line? [br][br]2. What do you think causes the difference between the shaded area?
Determine which inequality will be true for the point A=(2, -1). Use pen and paper to work out the problem. [br][br]y < x - 3 or [math]y\ge x-3[/math][br][br]Describe below what did you do.
Scroll up do [b]Graph app C[/b] and [b]Graph app D[/b] and plot point [b]A=(2, -1)[/b] The point will lay on the line. Using your answer from [b]Algebra work[/b], what do you think it means if a point will be on dashed line compared to solid line?
