Virtual Nerd: How Do You Find the Rate of Change Between Two Points on a Graph?

This tutorial shows how to use the information given in a table to find the rate of change between the values in the table. [3:46]

The instructor uses a graph representing time and distance to illustrate how to solve this word problem. She explains each step: rate of change, distance, time, vertical change over horizontal change, change in distance, and change in...

Given a table of values, find the rate of change. First, set up the given table, and identify the values that will be used to calculate the change. Of course, there is a formula. So use the formula to solve the problem. Still confused?...

Tutorial illustrates how to find the slope of a line by first identifying two points on a graphed line then using these points to calculate the slope. [3:03]

Instructional video shows how to use the distance formula to find the distance between two points. [2:29]

How do you find the factors of a given number? The teacher will show you how to use a table, test out your answers, and then write all your factors in a list. If you know the divisibility rules, that will also help you out.

Review for the SAT by reviewing how to figure out if the values in a replacement set are part of a solution set to an inequality. Watch this video for an example. [2:03]

Review for your SAT by brushing up on Venn diagrams. Watch this video on how to find the union and intersection of sets. [1:58]

Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...

The rate of change between points describes how quickly one variable changes relative to another. The video instruction concentrates on calculating the slope between two points using the slope formula. The instructor first explains the...
