This video provides a step-by-step tutorial on using the slope formula. In this example the slope is undefined. Note the download is a PDF that can used to demonstrate the step-by-step calculations.

In this video students learn how to calculate the slope of a line, given two coordinates. This is done by measuring the rise and the run and is a precursor to learning to use the slope formula. The video also discusses positive and negative slopes.

Using the context of staircases, this video explores the basic idea of slope. The video defines slope as a ratio and provides examples of calculating slope using the ratio of the rise over the run.

Topic

Linear Functions

Description

Applies linear functions to cycling, calculating hill grades and distances using slope formulas and graphing.

Linear functions are fundamental in understanding mathematical relationships between two variables. The video demonstrates their application in real-life scenarios, enhancing comprehension of key concepts like slope, intercepts, and graphical representation. This foundational knowledge prepares students for more advanced mathematical topics.

In this Math Lab we explore slope in the context of the steepness of staircases. This video is Segment 2 of a 4 segment series related to Algebra Nspirations: Linear Functions.

In this TI-Nspire CX tutorial, the Graph Window is used to calculate the slope of the line between two points. The text window is used to generate a formula linked to coordinate values. Note: This video does not contain audio.

In this TI-Nspire CX tutorial, the Graph Window and Spreadsheet Window are used to calculate the slope of the line between two points. The coordinates of the points are linked to variables, which are then used in the Spreadsheet Window to calculate the slope. The split-screen, dynamically linked windows allow you to manipulate the points, while getting an updated value for the slope. Note: This video does not include audio.

In this Nspire CX tutorial, randomly create two points in a Spreadsheet Window. Graph them as a scatterplot. Connect the two points using the Line tool, then measure the slope of the line. Creating new random coordinates will yield a new line with a new slope. Note: This video does not include audio.

In this TI-Nspire CX tutorial, use the Geometry tools to construct a line whose measurements for the rise and run can be used to calculate the slope. Note: This video does not contain audio.

In this Nspire CX tutorial learn how to find the slope between two points connected by a line.

In this Nspire CX tutorial linear functions in slope-intercept form are graphed using sliders.

In this TI Nspire tutorial for the TI-Nspire CAS, the Calculator Window is used to create a function to calculate the slope. This video supports the TI-Nspire Clickpad and Touchpad.

In this TI Nspire tutorial, the Graph window is to find the slope of two points connected by a line. This video supports the TI-Nspire Clickpad and Touchpad.
