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 -

https://www.youtube.com/watch?v=jG_sadWWtvI

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.

3. When using the slope-intercept form to graph linear
inequalities, how do you know which side of the line to shade
on?
4. What is an alternative method that can be use to indicate
that the appropriate regions are shaded correctly? Be sure to
explain how you would know this method indicates the shading is
correct or incorrect.
5. When graphing the shaded regions for a system of linear
inequalities, what indicates the solution set of the system?

1. Analyze and interpret graphs
2. Graph linear equations, inequalities and functions using a
variety of techniques
3. Find the average rate of change for application problems
4. Write linear equations in slope-intercept, point-slope and
standard forms
5. Model real-world problems using functions
Describe in a word document how you will be able to use these
objectives in both your personal and professional lives.

How do I create this table on TI 84 Plus?
If $1 dollar is deposited in an account paying 28% per year
compounded annually, then after t years the account will contain
y=(1+0.28)t=1.28t dollars.
(a) Use a calculator to complete the table.
(b) Graph 1.28t.

How can I use a graphing calculator to find areas of a normal
distribution graph

How can I do this on TI-84 Calculator Use technology to
construct the confidence intervals for the population variance
sigmasquared and the population standard deviation sigma. Assume
the sample is taken from a normally distributed population.
cequals0.95, ssquaredequals7.84, nequals28 The confidence
interval for the population variance is ( nothing, nothing).

Use the table below to find the correlation coefficient and then
determine whether there is a linear relation between x and y. You
can use hand or calculator to find r this time.
x 0 5 7 8 9 y 3 8 6 9 4
A r = 0.4403, no there is no linear relation between x and y
B r = 0.3304, yes there is a linear relation between x and y
C r = 0.4403, yes there is...

1. Use the x- and y- intercepts to graph each linear
equation.(Do not use graph paper)
a) 2x-5y=10
b) 3x=2y+6
2. Calculate the slope of the line passing through the given
points. If the slope is undefined, so state, Then indicate whether
the line rises, falls, is horizontal or is vertical.
a) (4,2) and (3,4)
b) (-1,3) and (2,4)
