## Can you do inequalities on a calculator?

The Inequality app on your TI-84 Plus calculator is a powerful mathematics tool. To start the Inequality app, press [APPS]. See the first screen. Then, press [ALPHA][x2] if necessary, use the down-arrow key to move the cursor to the Inequalz app, and press [ENTER] to select the app.

Can you graph inequalities on a TI-83 Plus?

An inequality graphing application is available for the TI-83 Plus and TI-84 Plus. It comes preloaded on the TI-84 Plus, and can be downloaded for the TI-83 Plus.

What are the steps to graphing inequalities?

Always start by isolating the variable\\color {red}y on the left side of the inequality.

• Change the inequality to equality symbol. For now,you will deal with a line.
• Graph the boundary line from step 2 in the XY- plane.
• The last step is to shade one side or region of the boundary line.
• ### How do you graph an inequality?

How do you solve and graph inequalities step by step? Step 1: Always start by isolating the variable y on the left side of the inequality. Step 2: Change the inequality to equality symbol. Step 3: Graph the boundary line from step 2 in the X Y − XY- XY−plane. Step 4: The last step is to shade one side or region of the boundary line.

How to graph and shade Intersecting Inequalities?

Rearrange the equation so “y” is on the left and everything else on the right.

• Plot the ” y= ” line (make it a solid line for y≤ or y≥,and a dashed line for y< or y>)
• Shade above the line for a “greater than” ( y> or y≥) or below the line for a “less than” ( y< or y≤ ).
• How do you calculate an inequality?

Eliminate fractions (multiplying all terms by the least common denominator of all fractions).

• Simplify (combine like terms on each side of the inequality).
• Add or subtract quantities (unknown on one side and the numbers on the other).
