An introduction to calculating the slope of a line. [Algebra: Lesson 8 of 86]
This continues the discussion of how to determine the slope of a line. [Algebra: Lesson 9 of 86]
A demonstration of calculating the slope of a line. [Algebra: Lesson 10 of 86]
Explanation of using the graph of a line module to understand how a line's graph changes when its slope or y-intercept is changed. [Algebra: Lesson 12 of 86]
This 9-minute video lesson looks at how to find the slope of a tangent line to a curve (the derivative). Introduction to Calculus.[Calculus playlist: Lesson 15 of 156]
This 10-minute video lesson covers more intuition of what a derivative is. It looks at using the derivative to find the slope at any point along f(x)=x^2. [Calculus playlist: Lesson 16 of 156]
This 8-minute video lesson covers the Calculus-Derivative: Finding the slope (or derivative) of a curve at a particular point. [Calculus playlist: Lesson 13 of 156]
This contemporary calculus course is the third in a three-part sequence. In this course students continue to explore the concepts, applications, and techniques of Calculus - the mathematics of change. Calculus has wide-spread application in science, economics and engineering, and is a foundation college course for further work in these areas. This is a required class for most science and mathematics majors.

This 10-minute video lesson provides an intuition on what happens to the slope/derivative and second derivatives at local maxima and minima. [Calculus playlist: Lesson 40 of 156]
An interactive applet and associated web page that demonstrate the equation of a line in point-slope form. The user can move a slider that controls the slope, and can drag the point that defines the line. The graph changes accordingly and equation for the line is continuously recalculated with every slider and / or point move. The grid, axis pointers and coordinates can be turned on and off. The equation display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of the equation of a line in point - slope form, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
An interactive applet and associated web page that demonstrate the equation of a line in coordinate geometry. The equation is in the form y=mx+b. The user can move two sliders that control a and b. The graph changes accordingly and equation for the line is continuously recalculated with every slider move. The grid, axis pointers and coordinates can be turned on and off. The equation display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts.

This module discusses lines and their uses, and slope.
This module provides practice problems designed to develop some concepts related to graphing lines.
Using a graphic calculator to compare the slope and y-intercept of lines to understand the slope-intercept form (y = mx+b) and what effect each has on a line.
This 10-minute video lesson looks at understanding why distance is area under velocity-time line. [Physics playlist: Lesson 11 of 164].
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device. During a hands-on activity, students see how the angle of inclination and pull force can make it easier (or harder) to pull an object up an inclined plane.
An interactive applet and associated web page that demonstrate the slope (m) of a line. The applet has two points that define a line. As the user drags either point it continuously recalculates the slope. The rise and run are drawn to show the two elements used in the calculation. The grid, axis pointers and coordinates can be turned on and off. The slope calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of slope, a worked example and has links to other pages relating to coordinate geometry.

This Website contains over 200 authentic math problems that cover solar physics, space physics, radiation dosimetry, and the human impacts of space weather. The problems range from pre-algebra to calculus and span the math skills appropriate for grade 8-12 students. The problems are taken from authentic applications of arithmetic, graph analysis, pre-algebra, and algebra.
The student will determine the correlation between two variables. They will graph ordered pairs on a coordinate plane, determine a best fit line, find slope and intercepts, and write the equation of a line. This lesson plan is geared for both 8th grade math and algebra.
This lesson demonstrates the effects of changing the slope and y-intercept on the graph and equation of a line.
