Linear equations and inequalities are fundamental concepts in algebra, and they are also an important part of the SAT Math section. Linear equations represent straight lines on a graph and can be used to model many realworld situations, such as the growth of a population or the depreciation of an asset over time. Inequalities, on the other hand, represent a range of possible values and are often used to express constraints or limitations in a given situation.
On the SAT, linear equations and inequalities are tested in a variety of ways, including solving equations for a given variable, graphing equations and inequalities, and using equations to solve word problems. By mastering these concepts, you'll be better equipped to tackle the SAT Math section and succeed in your college admissions journey.
To help you prepare for the SAT Math section, we've created a practice test for linear equations and inequalities. This test will give you the opportunity to practice solving problems similar to those you'll encounter on the SAT. As always, should you have any trouble with the questions on this test, don't hesitate to reach out for personalized SAT tutoring to help you ace this section.
Good luck!
