Description
Exercise Name: Interpreting and solving linear inequalities
Math Missions: 7th grade (U.S.) Math Mission, Algebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission Mathematics II Math Mission
Types of Problems: 3

The Interpreting and solving linear inequalities exercise appears under the 7th grade (U.S.) Math Mission, Algebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission and Mathematics II Math Mission. This exercise practice working with linear inequalities.

## Types of Problems

There are three types of problems in this exercise:

1. Write inequality and find correct graph: This problem provides an inequality and four number line graphs. The user is expected to find the correct inequality and indicate the graph that correctly illustrates the inequality.
2. Write an initial inequality and solve: This problem has a word problem that involves an inequality. Users are is expected to write the inequality and solve the inequality.
3. Write inequality and find numerical solution: This problem has an inequality in a word problem. The user is asked to write the inequality and provide a reasonable answer to the question asked.

## Strategies

Confidence with word problems and an ability to translate between English and math are the greatest advantages.

1. If the $x$ is isolated on the left, then the inequality as an "arrowhead" faces the direction that should be shaded.

## Real-life Applications

1. For most people, in order to get their license they have to be at least 16. So, they can write this as an inequality. ${x}$ is the age of a person who wants to drive. In this case ${x}$ has to be greater than or equal to 16.
2. Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
