Equations Inequalities And Problem Solving

If you get a false statement, then the ordered pair is not a solution.

Take a look at this tutorial and learn how to determine if an ordered pair is a solution to an inequality!

In this tutorial you'll learn what an inequality is, and you'll see all the common inequality symbols that you're likely to see :) Knowing the definition for a compound inequality is one thing, but being able to identify one in a word problem or phrase can be an entirely different challenge.

Arm yourself by learning some of the common phrases used to describe a compound inequality and an absolute value inequality.

Graphing inequalities on the coordinate plane is not as difficult as you might think, especially if you know what to do!

In this tutorial, you'll see the steps you need to follow to graph an inequality.

So, you proceeded to subtract 2 from both sides of the equation remembering that to keep an equation equal, whatever you do to one side you also must do to the other.

After subtracting 2 from both sides, your variable is alone and you have solved the linear equation. Now, let's say you are given a problem like x 2 You first solve the inequality by dividing each side of the inequality by -3. Now, flip the symbol to get your solution: x less than or equal to -2.

Then draw a straight line left and right that goes through the point, and you're done!

When you're learning about linear equations, you're bound to run into the point-slope form of a line.
