Shows how to ofirst find the coordinates of the vertex, then choose other inputs to find two more points on each side of the vertex, plott them and draw the graph.


Shows how to shoose appropriatate input values to find five points, then plot them and draw the graph.


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


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…


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.


Shows how to interpret and graph on a number line a set written in set builder notation, then goes on to transfer the line graph to interval notation.


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


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…


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


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…
