Let's explore different ways to find and visualize slopes and intercepts, and how these concepts can help us solve real-world problems. **Unit guides are here!**

Learn to determine if a table of values represents a linear function. Created by Sal Khan.

The definition of a function is that each input creates only one output value. For a function to have an inverse, the relationship must be that there is a 1-to-1 relationship between its input values and its …

Not all functions have an absolute maximum or minimum value on their entire domain. For example, the linear function f (x) = x doesn't have an absolute minimum or maximum (it can be as low or as high …

Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both …

Linear functions are usually written in either slope-intercept form or standard form. We need a thorough and flexible understanding of these forms in order to approach many SAT questions about linear …

This topic covers: - Adding, subtracting, and multiplying polynomial expressions - Factoring polynomial expressions as the product of linear factors - Dividing polynomial expressions - Proving polynomials …
