## Solving One Variable Equations

One-Step, Two-Step and Multi-Step equation solving examples for basic algebra.

## Graph from slope-intercept equation

To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=2x+3 tells us that the slope of the line is 2 and the y-intercept is at (0,3). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.

## How to find the rate of change between two points on a graph.

The rate of change is a rate that describes how one quantity changes in relation to another quantity. In this tutorial, practice finding the rate of change using a graph.

## Graphing vertical and horizontal lines

Graphing horizontal and vertical lines in the x-y plane.

## How do you graph a linear equation by making a table

Graphing a function? It would be really helpful if you had a table of values that fit your equation. You could plot those values on a coordinate plane and connect the point to make your graph. See it all in this tutorial!

## Graphing linear equates by plotting points
