How Do You Find the Distance Between Two Points?

Here is an introduction to solving simultaneous linear equations. Start by drawing a line through two points. Create a second line which goes through the intersecting point. Background knowledge of how to find the equation of a line and...

Can an equation have an infinite number of solutions? Allow your class to discover the relationship between the input and output variables in a two-variable equation. Class members explore the concept through tables and graphs and...

When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

Point out an application of Pythagoras. The segment of an essential playlist on geometry provides a quick review of the Pythagorean Theorem. Using a right triangle to show the positions of two points, the presenter calculates the...

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 teacher demonstrates how to plug in values from two given points to find the slope of a line. She uses the slope formula and goes through the problem step-by-step.

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...

Learn how to use an algebraic formula to find the distance between two given points on a coordinate plane.

There are a lot of steps in this problem. But just like walking up a flight of stairs, you should take one step at a time, so too in the solving of this problem. The instructor explains each step and what to do to move to the next one.

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