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.


A twostep process involving first removing the greatest common factor from both terms, then factoring the resulting difference of squares.


Shows how to determine the boderline separating the side of the xy graph that has true solutions from the side that does not. It is then shown how to decide whether that line should be dotted or…


Demonstates how to interpret a graph of a system of functions so that common questions that someone might have can be answered.


Looks at the three types of graphs that can occur with a system of two linear equaltions in two variables.


Demonstrates how to make t his graph per instructions, and also shows how to deal with a fractional leading coefficient.


Shows how thits form is simply the same as y = mx + b, and then writes the slope and yintercpt down. It ends with using these to graph the line of points that satisfy this function.


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


Shows how to write the domain and range of a graph of an unbroken function with a starting point and an ending point.


This demonstrates why and how to use vertical lines to test whether a graph of any relation is a function or not.


We use the slope formula to find the slope from the given points, then we use it again, inserting the discovered slope and solving for the desired missing coordintate of a third point.


Using the slope formula, we enter the given information and then solve for the unknown coordinate.


Shows how to interpret a situatioin and create an equation that creates a mathematical connection between two variables. Then by substituting a couple of input values, we can determine the outputs…


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…


Shows how you can create the pointslope form, then shows the entry of the given information.


Demonstrates how to solve a standard form equation for y to get the slopeintercept form y = mx + b
