This resource demonstrates how to solve linear inequalities step-by-step and shows four different solution formats/notations viz. inequality notation, set notation, interval notation, and the last "notation" which is more of an...

Students will participate in this discovery activity intended for them to uncover the role each variable plays in the graph of a line in the form y = mx + b. Students will actually demonstrate lines in slope intercept form on a life size...

[Free Registration/Login Required] Presents the definition of slope and the formulas for y-intercept form.

Purplemath gives the fundamentals of matrices. Begins with linear equations of three variables and shows the corresponding matrix. Discusses the augmented and coefficient matrix formed from the equation. The size of a matrix and special...

Students input a function in either y= of f(x)= form, and then the site from WyzAnt does the rest! A detailed graph is shown in less than a second. Students can change the window used to view the graph as well as whether to have...

Enter the slope and y-intercept of any line and it will be graphed for you. This site is great for becoming familiar with the concept of graphing and for checking your own graphs. Requires Java.

A discussion on how to solve linear and nonlinear inequalities is presented. Both the Test Method and the Factor Method of checking positive/negative intervals are included as part of the discussion.

Interactive activities that will help you solve first degree equations with one unknown in graphical and numerical form.

Students watch an online tutorial on the concept of graphing using slope intercept form. After watching, students test their knowledge by attempting ten practice problems that increase or decrease in difficulty based on their answers.

This activity is intended to be a discovery activity for students to determine the effect that changing m and b have on the equation y=mx+b. There is a teacher guide and an activity to determine the student's level of understanding.

This activity focuses on strengthening student understanding of connections among graphical, tabular, and algebraic representations of simple linear functions. They enter a simple program that allows them to determine the equations for...

A two-part activity that uses a CBR to develop the notion of slope and y-intercept through various walking activities. Part A develops a general notion of how changes in walking are reflected in various graphical representations. Part B...

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the...

Solve quadratic equations of the form x^2+bx+c=0 that can be rewritten according to their linear factors. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Solve quadratic equations of the form ax^2+bx+c=0 that can be rewritten according to their linear factors. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Number patterns can be made with any of the operations or combination of operations. Range and domain of any function can be listed in a table. When these functions are linear, the equation can be written in slope intercept form.

Solve quadratic equations of the form ax^2+bx+c=0 that can be rewritten according to their linear factors.

Solve quadratic equations of the form x^2+bx+c=0 that can be rewritten according to their linear factors.
