Calculating the Shortest 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...

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...

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...

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...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

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...

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

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.

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.
