Geometry problems on the SAT are often the most difficult for students to solve, let alone master. Focusing on several geometry-related skills (as well a few algebra problems), Sal makes this lesson a valuable resource for viewers who...

Teaching slope is part of the foundation for graphing equations. This video starts at the beginning and introduces the types of slope before calculating with the slope formula. On a graph, your learners will see that every line has a...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

This word problem has only one set of given numbers. How does one make a graph with only one set of numbers? Make a table to get the other set of values. Now these values make ordered pairs and can be plotted on a graph.

Finding the domain and range of the inverse of a relation can be tricky, unless you know the correct steps! It's not that complicated. Watch this video and see how the instructor does the inverse of a relation before writing the domain...

Order is important! An ordered pair is comprised of an x-value, and a y-value. The x-value always comes first. This ordered pair represents a point on a coordinate plane. If the order of the x-value and the y-value are switched then they...

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...

One way to solve a system of equations is to graph two equations and find the point of intersection. This method is demonstrated on a whiteboard to help your mathematicians understand the concept. An easy way to check your solution is...

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...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

A function means that every element of the domain is paired with exactly one element in the range. The teacher illustrates this by using a table for the given set of numbers.

The instructor shows how to write the inverse of a relation. In a set of ordered pairs, she takes each pair of coordinates and flips the order, getting the inverse.
