The informaton given here can be entered directly into the y = mx + b or slope-intercept form. Then the y-intercept is used as a starting point where you apply rise over run to the given slope to…

Another demo on how to use the y-intercept to start a graph of a linear equation and then use the slope to find other points on the graph. It finishes with showing the line representing all of the…

A demo that shows how to substitute possible x-y ordered pairs into an equation to find out whether they create a true statement, determining which are solutions and which are not.
|
|
This explains how to use the slope and y-intercept to determine points on the line graph of a linear equation in two variables and then draws the straight line graph.

Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results
|
|
This contains one example of solving an inequality as described in the title.
|
|
A quick demonstration of how to interpret a line graph of a compound inequality and write its algebraic form.
|
|
An examplel of how to rearrange a formula to better suit its particular purpose. Often we need to do this because it is easier to rearrange it once instead of having to solve for a variable each…

|
A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.
|
|
This describes how integers interact when combined, treating minus signs as a negative sign on the number and thinking that all of the integers are being added with negatives and postives working in…

|
Two examples that show different possible results from solving a radical equation. You must always check the answer to these.
|
|
Shows how these forms are interrelated
|
|
This has two examples so that you can learn to watch out for what looks like a solution but is not because it creates division by zero if you check the answer in the original equation. The other…

|
Shows cross multipication of two single fractions set equat to each other to create a new equation that has no fractions and is then solvable by the typical methods.
|
|
Demonstrates how to multiply a single term by an expression with more than one term but containied in parentheses. using distribution.
|
|
Shows how to write the domain and range of a graph of an unbroken function with a starting point and an ending point.
