When you hear the word "geometry", you might think of shapes. And you wouldn't be wrong! But before we can get to shapes, we need to talk about the parts that can make up shapes, like points, lines, rays, and line segments. In this...

In this video, the teacher explains how to identify a system of linear equations with no solution. They discuss the concept of parallel lines and demonstrate how to solve each answer choice to determine if it has a solution or not. The...

MIT has announced that they will be investing $1 Billion in AI research, in the form of a new College of Computing. But what does that mean?

“Identify Extraneous Solutions” will review the different methods of how to test equations for extraneous solutions.

You will solve for the point of intersection of two linear equation problems with two variables.

This video provides instruction on how to construct an angle bisector for a given angle.

“Systems of Equations” will explain how to tell whether two lines intersect, and if they intersect, how to solve them.

The intuition and implications of the complex derivative

In this video lesson, you will learn how to graph a system of linear equations and solve them by identifying the point of intersection. You will also learn how to check your solutions to ensure they are true for both equations in the...

In this video, the teacher explains how to find the measures of angles formed by parallel lines and a transversal. They use the properties of supplementary angles, alternate interior angles, and the triangle sum theorem to solve for the...

In this video, the teacher uses angle facts to solve math problems. The students are given a diagram with intersecting lines and angles, and they are asked to write algebraic equations to find the values of X and Y. The teacher walks...

When the elimination method is used to solve a system of linear equations, viewing the geometrical changes that happen to the system during this process can give insight into the mechanisms which underlie the logic behind the algebraic...

In this video, you will learn how to write a system of equations to solve story problems with multiple unknowns. The goal is to find the solutions that satisfy each equation in the system. You will also explore different methods to solve...

This video explains how mathematicians use coordinate planes to show the location of objects in space. It introduces the concept of horizontal and vertical number lines, which intersect at the origin to create a coordinate plane. The...

👉 Learn how to take the derivative of a function. Learn how to find the derivative of a function using the chain rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the...

In this video, the teacher explains how to find the x-intercepts of a quadratic function by factoring. They clarify the difference between y-intercepts and x-intercepts and demonstrate how to use the zero product property to find the...

In this lesson, students will learn how to estimate the solution of a system of equations by graphing. They will review the concept of intercepts and how to find them. By graphing the equations and identifying the point of intersection,...

In this lesson, students will learn how to determine if two lines intersect. They will explore the concept of parallel lines and perpendicular lines, and understand that parallel lines have the same slope.

In this video, the teacher explains how to determine the shape of a cross section when slicing a three-dimensional solid, using the example of the Great Pyramids of Giza.

In this video, students learn how to solve pairs of linear equations by using patterns. They explore the concept of solutions to linear systems and how they can be represented graphically. By analyzing the slopes and y-intercepts of the...

When the graph of the solutions of a system of linear equations in three variables is a line in Cartesian space, the solutions can be described either by a group of three parametric equations, or a parametric ordered-triple. This lecture...

It's not enough to just consider the number of sides in a quadrilateral, we must also consider the congruence of sides, the types of angles formed, and the presence of parallel or perpendicular lines. Using a square as an example, we...

Constance Steinkuehler is an Associate Professor in Digital Media at the University of Wisconsin–Madison and co-directs the Games+Learning+Society (GLS) center at the Wisconsin Institute of Discovery and chairs their annual GLS...

Systems of two linear equations in two variables can have a single solution, no solutions, or an infinite number of solutions. This chapter explains why.
