Students build bridges and test their strength to collect data and write an equation. The concept of slope is explored in this activity.

A collection of activities where students investigate linear equations. Activities involve an exploration of the lines in a polygraph and the vocabulary needed to describe them accurately; the slope in graphs; lines in different...

Given a quadratic equation, the student will use graphical methods to solve the equation.

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...

Given the graph of a situation represented by a quadratic function, the student will analyze the graph and draw conclusions.

Students groups act as aerospace engineering teams competing to create linear equations to guide space shuttles safely through obstacles generated by a modeling game in level-based rounds. Each round provides a different configuration of...

A tutorial on how to find the line of best fit or least-squares regression line for a set of data in a scatter plot using different methods and calculations.

In this activity, students explore the standard form of a quadratic equation, y = ax 2 + bx + c. They explore how the x-intercepts (zeros), y-intercept, and vertex are related to the graph of the standard form of a quadratic function.

Students learn to use measurements on a real model to develop the concept of slope and linear functions. They use a calculator to explore changing the slopes and Y- intercepts in the slope intercept form Y = MX + B.

[Free Registration/Login may be required to access all resource tools.] This lesson covers how to find the x-intercepts, vertex, axis of symmetry, and y-intercept of a parabola.

The Function Analyzer allows learners to see the connections among three representations of a function: symbolic, area, and graphic. In addition, by allowing learners to change the value of four elements of a function - the coefficient...

Students can use TI 73 calculators to explore equations that create parallel and perpendicular lines. Teacher will use the screen capture feature of the Navigator system to display students graphs and equations to discuss observations to...

The student is given actual data and asked to find a line of best fit and to give "real world" interpretations of the slope and y-intercept. A great introduction to the 83/84 and its features.

Students can use a graphing calculator to explore graphs of parallel and perpendicular lines. Students will find that parallel lines have the same slope and different y-intercepts and that the slopes of two perpendicular lines are...

Students recognize and know the sketches of quadratics, cubics and recipricols including the shape of positive and negative functions and the interpretation of their y-intercepts.

[Free Registration/Login may be required to access all resource tools.] Write linear equations in standard form and find the slope and y-intercept of such lines.

Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ("roots") of the function, and the vertex of the parabola. Students...

[Free Registration/Login may be required to access all resource tools.] In this lesson students use ''X'' and ''Y'' intercepts to graph polynomials of 3rd degree or higher. Students examine guided notes, review guided practice, watch...

Use this interactive graph to gain an understanding of how taxes increase as your income goes up. The y-intercept line shows the base tax amount for no income.

This lesson is a technology-based activity in which students extend graphing of linear functions to the use of spreadsheet software. After students have become proficient in constructing a table of values, students are able to...

Identify the form of a quadratic function that immediately reveals a given feature of that function. Features in question are the y-intercept of the graph, the zeroes ('roots') of the function, and the vertex of the parabola.

Explore the relationship between degrees Fahrenheit and degrees Celsius. This video focuses on developing an expression to model the relationship between the temperature scales using a line graph to calculate slope and the y intercept.

This site from the Northeast Parallel Architectures Center, Syracuse University has a very substantial discussion of math topics slope & line equations. The outline form is quite useful if you need to zero in on one aspect of...

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...
