The process to solve linear inequalities in a variable is similar to solving basic equations. Most of the rules or techniques used to solve equations can be easily used to resolve inequalities. The only important difference is that the symbol of inequality changes...

The equation of a line can be found through various methods depending on the information available. The two points form is one of those methods. This form is used to find the equation of a line that passes through two given points. Here, we will look at how to find...

Quadratic functions are polynomial functions that have a maximum degree of two. The graphs of quadratic functions are called parabolas and have a “U” shape. Quadratic functions can be used to model various situations in everyday life such as the parabolic motion...

A linear function is defined as a function that has one or more variables without exponents. Linear functions produce straight lines when graphed. Here, we are going to do a brief review of linear functions. We will look at how to graph linear functions and how to...

Proportionality allows us to relate two or more quantities. In the case of compound proportionality, we are relating three quantities at the same time. Compound proportionality is represented as y∝xz. If we use the constant k, we can form the...
