Here is another puzzle that is related to graph theory. In a small village there are three utility plants producing water, electricity and gas respectively. There are also three houses which need to be served. Unfortunately, due to the...

Young scholars love graphing data that they "own". In this plan, the class will select a type of graph and create it using a class survey frequency table. Included in this lesson are videos of the class engaged in the lesson and samples...

Use this activity to practice how to enter a set of data, plot the data on a coordinate grid, and determine the equation for a line of best fit.

The interactive resource investigates slope and intercept. Students adjust the sliders to control the slope (m) and the intercept (b) of the line. The equation and the line will change accordingly. Learners can also drag the origin.

A simple tutorial that will show you how to graph linear equations and functions after finding the x- and y-intercepts. Provides definitions, steps for sketching a graph, and several examples of linear equations and their graphs....

On this interactive website students practice various math skills using a real-life scenario involving plants. Those skills include interpreting data in a circle graph, interpreting data in a divided bar graph, and interpreting a bar...

This is a graphing tool for economics students that allows you to draw curves, lines, tick marks, etc. Also gives students the ability to label the axis and print the graph. Sample problem included.

Thyis site offers problem solving systems and graphing systems of inequalities. Illustrations included.

A comprehensive guide for learning all about line graphs with definitions, their sections, how to read and create graphs, solved examples, and practice questions.

Demonstrates, step-by-step and with illustrations, how to use slope and the y-intercept to graph straight lines.

A good introduction to reading bar, line, and double line graphs, and drawing and reading Venn diagrams. Contains definitions and examples of these types of charts and graphs as well as practice exercises that ask you to answer questions...

[Free Registration/Login may be required to access all resource tools.] Students learn to use a table to graph functions recognizing linear equations and the equations of horizontal lines and vertical lines. Students examine guided...

This CoolMath Resource will help students determine if lines are perpendicular by finding the slope, using the point-slope formula, and graphing.

Provides examples and a video lesson that illustrate line plots and stem-and-leaf plots. [1:12]

This CoolMath resource provides a review of horizontal and vertical lines.

This robust lesson plan for upper elementary and middle school grades introduces the concepts for lines, rays, line segments, and planes. Resources are linked to it and ready for your use.

Practice using your graphing calculator for geometry problems, including the use of the Pythagorean Theorem and the distance formula. If you get stumped or if you would like to check your work, then select the View Solution button, which...

The most basic quadratic is y = x2. The general technique for graphing quadratics is the same as for graphing linear equations. The quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear...

Students gain the knowledge of how to plot and recognize first degree equations on a graph. The lesson has an overview, materials, procedures, and evaluation techniques.

A detailed tutorial on functions covering the following topics: finding the domain and range of a function, using the vertical line test, determining whether a function is even, odd, or neither, and applying the greatest integer function...

Math picture graphs for kids. Pie, line, and bar charts. Learn with problems, examples.

Here is a site that clearly and thoroughly explains the equation of a line, including how to find points on a line, intercepts, and how to recognize the equation of a line. There are example problems solved, problems for the student to...

In this physics tutorial, examine how the actual slope value of any straight line on a PT graph is the velocity of the object.

Discover the importance of finding the equations of lines.
