This shows the method of using the point-slope form to write the equation, then solving that form for y to get y = mx + b.
|
|
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.
|
|
Shows one example of solving a iinear inequality in two steps.
|
|
This demo takes some thought so you may want to watch it a few times to fully understand. Writing the expression and then we simplify it so that it is more usable in future.
|
|
This video demonstrates how to change a description in words into an algebraic expression.
|
|
A short demo involving subtracting whole numbers from both sides of an equation. There are two examples.
|

Given a value for the variable, here a quadratic expression is then calculated with that given value put in place of the variable.
|
|
A quick demo about plugging in given values for variables and calculating a number result.

This demonstrates how to find these values for a quadratic equation of the form y = ax^2 + bx + c.
|
|
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
|

|
Two examples here of solving radical equations. Both have one radical that each need isotation before squaring both sides.. Emphasis is p laced on checking your answer because the one arrived at…
|
|
Squaring both sides of this equation means squaring a binomial. This is demonstrated by this video.
|
|
This radical equation when sqaured to eliminate the sqaure root creates a quadratic equation that can then be solved by factoring.
|
|
Two examples that show different possible results from solving a radical equation. You must always check the answer to these.
