The graph of a line with an undefined slope is a vertical line. Why is it undefined? It has something to do with the value of the x-coordinate. The x-coordinate determines the run of the slope. So what if the run is zero? The instructor...

It only takes the denominator to be zero to make an expression undefined. A video resource makes the connection of undefined fractions to rational expressions. It points out that to determine when a rational expression is undefined, you...

Defining the undefined is the goal of this video. The instructor explains the important features of a point, line, and plane and how they work together. He also addresses the correct ways to name each and describes the correct notation —...

Introduce the idea of an undefined solution to your classes. The video instructor simplifies several problems that result in division by zero and an undefined result.

Tenth graders define terminologies related to geometry. In this geometry instructional activity, 10th graders discuss undefined terms, line segment and ray. They answer the question, how many points it takes to make a line.

Many times budding algebrists are fine when plugging specific numbers into expressions, but less certain when the range of acceptable values is undetermined. This detailed presentation helps the class move from the point value to the...

In this undefined fractions worksheet, 9th graders solve 10 different problems related to solving various undefined fractions. They determine the value of x in each that makes the fractions undefined. Students determine when the...

In this algebraic fractions worksheet, 9th graders solve 10 different problems that include various undefined algebraic fractions. They determine the value for each variable that makes the fraction undefined in each situation. Then,...

In this graphing rational functions worksheet, students answer 18 multiple choice problems about rational functions.  Students determine values for a which a function is undefined given the equation of the function.

In this equations and inequalities worksheet, 9th graders solve and graph 10 different problems that include determine the slope of a line. First, they determine the slope of a line represented by a given equation. Then, students...

This two-day lesson will help the class simplifying rational expressions. It also has an emphasis on understanding when a rational expression is undefined. The lesson contains powerpoint presentations, worksheets, and answer key.

Can you define that basic figure? Building upon the undefined terms in geometry, the lesson defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

We look at a number of different examples of functions and see what their domain is. Sal writes the domain in set notion and shows how different functions can have different input values that cause the function to be undefined.

Go back to where it all began! Investigate how axiomatic systems and Euclidean geometry are based on undefined terms, common notions, postulates, and propositions by examining passages from Euclid's Elements. (Social studies teachers...

Pupils build on previous experience with slope to investigate positive, negative, zero, and undefined slope. They complete a puzzle matching slope-intercept and standard forms of linear equations.

In this slope of a line worksheet, 9th graders solve and graph 10 different problems that include determining the slope of a line. First, they determine the slope of a line that contains two given points. Then, students determine the...

Teach your scholars about shape attributes using this brief worksheet, which could be used as an all-class warm-up. There are three sets of shapes for learners to assess here. First, they count the number of triangles, then shade the...

Looking for a great handout on slope? This resource makes a great study guide with the definition, diagrams, and the formula. Learners use coordinates to calculate the slope of lines. Positive, negative, zero, and undefined slope...

Videos are a useful instructional tool with versatile application. Here is a video that reviews the process of finding limits for rational expressions with undefined points. It outlines the algebraic method of factoring and reinforces...

Learning about slopes from a hike in the woods is a walk in the park. Scholars slide a cutout of a person to simulate a hike along several paths. Passing through indicated points reveals the type of slope (positive, negative, zero, or...

Use slope to find the location of horizontal and vertical tangent lines. Using the derivative of a radical function, the presenter finds the points where the derivative is zero or undefined on a given interval. The 26th in a series of 31...

What's the value of 0^0? It turns out that there's a bit of controversy. A short YouTube video describes different interpretations of the value of the expression. It shows the case for 0^0 being undefined and the case for 0^0 being equal...

Middle schoolers use a computer to complete activitites about slope. They find the slope of mountains, roofs, and stairs using rise over run. Pupils are shown different types of slopes and have to identify if the slope is positive,...
