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


Another demo on how to use the yintercept 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…


Just a short demo of how read the location of an (x, y) point on a Cartesian coordinate 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


A demonstration of how to deal with interpreting the union and intersection of two inequalities. For a more extensive and exhaustive demo, please view the videos entitled "Understanding…


This presents how to graph two inequalities that are connected by either the word "or" or the word "and"


A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.


This shows how to find the vertex of a parabola and then calculate the matching points one unit and two units to the left and right of hte axis of symmetry


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…


Application of the equation relating the three sides of a right triangle:: a^2 + b^2 = c^2 where a and b are the shorter sides that make the rigiht angle and c is the lenght of the longest side.


The key to getting this type of question is distributing any minus sign on the outside of the parentheses to each term on the inside thereby changing all of the i nner signs to their opposite


Negative powers of 10 means that they are very small fractions.


Just showiing how to locate and write down the xintercepts and yintecepts when looking at a graph


Need the videos for finding tej slopes of parallel and perpendicular lines before viewing this one. This shows how to get the infromation needed for fulling in the pointslope form. You can leave…


Consists of locating the given point and then using the slope to find other points along a l line, then lastly drawing the line.


Demonstrates how to start at the yinitercept point on the grid and then use the slope to find other points on the line graph.
