Two very clear examples of point-slope form are given in this Purplemath lesson. One example begins with the slope and a point and the other example begins with two points. Includes interactive widget for practice determining a linear...

A tutorial on slope with many step-by-step examples. The tutorial clarifies what slope is, how to find slope between two points on a graph, and how slopes of parallel and perpendicular lines are related.

Slope-intercept form of a line is shown in formulas and examples with this Purplemath lesson. There are examples of slope-intercept with the slope and a point and with two points. Includes interactive widgets for exploring concepts.

Eighth graders work with slopes and similar triangles in this problem and will learn why the calculated slope will be the same for any two points on a given line. Aligns with 8.EE.B.6.

This lesson will use a slide presentation to facilitate teaching students how to find the slope of a line when given the graph of the line or two points. Students will interact with the presentation in two ways: first, by taking notes...

Learn how to graph lines with two methods: using x- and y-intercepts and using point-slope form.

Three different lessons demonstrate how to write linear equations. The equations found from two points, slope and a point, and slope and y-intercept are all featured. The lessons have an overview, materials, procedures, and evaluation...
