How Do You Graph a Line If You're Given the Slope and a Single Point?

For Teachers 6th - 12th
You have a slope and a given point and now you have to graph it. Begin by drawing a graph and then plotting the given point. Remember that slope is rise over run. So from the given point move the appropriate spaces to plot the next...

How Do You Graph Points in the Coordinate Plane?

For Teachers 6th - 12th
So you have an ordered pair and you want to graph it. Just remember that the first value is plotted along the x-axis and the second value in the pair is plotted along the y-axis. So count left or right, then up or down and you have...

How Do You Use a Graph to Reflect a Figure Over the X-Axis?

For Teachers 6th - 12th
A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the x-axis) and make the calculations to flip the figure.

How Do You Use the Vertical Line Test to Figure Out if a Graph is a Function?

For Teachers 6th - 12th
How does the vertical line test help you decide if the graph of an equation is a function? The instructor draws a graph and then draws the line of the equation. She demonstrates how to use the vertical line test to determine if the graph...
