Virtual Nerd:how Can You Tell if a Function Is Linear or Nonlinear From a Graph?

If you can write the equation in standard form, then it's a linear equation. Watching this tutorial to see how. [1:03]

The instructor demonstrates how to verify that a given point does or does not lie on the line of a given equation. She draws a graph (the axis lines need arrow ends) and plots the given linear equation. She then plots the coordinate...

The instructor demonstrates graphically how to verify that a given point lies on the line of a given equation. She graphs a line in slope-intercept form, and then plots the point to verify if it is in fact, on the graph of the line.

How can you tell if number relationships are proportional? Mathematicians investigate proportional relationships. They compare and contrast functions and graphs to determine the characteristics of proportional relationships, as well as...

In this video lesson a students learns how to determine if a triangle is a right triangle by using the Pythagorean Theorem.

In this video lesson students learn how to graph a system of equations that has no solution.

There are rabbits, rabbits, rabbits everywhere. Not this group of rabbits. Use a table to find some x and y values to create a graph to solve this word problem. It's a rather peculiar word problem in that it is trying to find when a...

Can it be determined if a given point satisfies the equation and is thus a point on the line of the graph? So given a coordinate point, plug the values into the equation and solve. If the solution is true, then the given point lies on...

Make a table to graph a rational equation. Make a list of values for x and plug them into the expression to get the y value. Then plot the ordered pairs on a graph. Hey, this graph looks funny! Something about asymptotes. Watch closely...

Set up a table to keep track of your values as you evaluate an exponential function. Select some values for the table to plug in to the given exponential expression. Then evaluate the expression. Do you see a pattern?
