Graphing Quadratic Equations

"When graphing quadratic equations, there are a few key terms that we can identify to help us graph quadratic functions more efficiently. Instead of plugging in values, we can find specific characteri ...

Solving Systems of Equations by Graphing

"A system of equations is two or more equations that contain the same variables. Solving systems of equations by graphing is one method to find the point that is a solution to both (or all) original e ...

Solving Literal Equations

"Sometimes we need to use methods for solving literal equations to rearrange formulas when we want to find a particular parameter or variable. Solving literal equations is often useful in real life si ...

Solving Linear Inequalities

"If we want to solve for or describe a region in a coordinate plane, we can use linear inequalities. Linear inequalities give us a set of solutions as opposed to just one solution. Solving linear ineq ...

Solving Linear Equations

"Equations are fundamental to Algebra, and solving linear equations is necessary for students in order to learn how to solve two-step equations, and other multi-step equations. Solving linear equation ...

Point-Slope Form of a Line

"Point-slope form of a line is one method to write the equation of a line. Start with the slope equation, which is basically the difference between two points, and then rearrange the terms to obtain ...

Mixture Problems

"Some word problems using systems of equations involve mixing two quantities with different prices. To solve mixture problems, knowledge of solving systems of equations. is necessary. Most often, the ...

Absolute Value Equations

"Solving for a variable in absolute value equations follows different rules than when we solve multi-step equations. When solving absolute value equations, most of the time we get more than one possi ...
