Question

D15: How do you use the TI-calculator to graph linear inequalities?

1. Find a video explaining this process and post the link. Here is a video that I found on YouTube explaining how to graph Linear Inequalities using the TI Calculator:

Explain how to graph x > 5 by hand and on the TI.

2. Explain how to graph y < 7 by hand and on the TI.

Answer 1

Solution -

1) Here is link of you tube -

2) For graphing line x>5

1) First we will graph line x = 5

We can make a table

  

x	5	5	5	5
y	0	1	2	-1

Now we will draw these points and make a dotted line passing through these points .

It is greater than sign so we will shade right side of line .

2) First we will graph line y = 7.

We can make a table

x	-1	0	1	2
y	7	7	7	7

We will draw a dotted line passing through these points .

It is y<7 so we will shade part below line y = 7.
