This demo discusses how to set up two equations to solve the situation described, and then choose the best method to use to solve for each of the variables.


This shows the method of using the pointslope form to write the equation, then solving that form for y to get y = mx + b.


This video describes why the method for finding the intercepts works, then demonstrates finding the intercepts for an example equation and graphing its line.


This explains how to use the slope and yintercept to determine points on the line graph of a linear equation in two variables and then draws the straight line graph.


Here we solve a rational equation by multiplying each of the terms in the equation by the LCD of all of the fractions. This allows us to divide to one all of the factors in the denominators and the…


Demonstrates what happens when the F.O.I.L. method is applied to multiply two binomails of the form (a + b) (a  b). It's special circumstance that allows a short cut.


Demonstrates how to read and understand the description so that equation can be made for a 2X2 system, then solve the system using and appropriate method.


Talks about how to interpret the words to create two equations, then solves them together using the elimination method, making opposites of one variable's terms sot that the equations can be…
