This resource provides an overview of graphing for various types of functions, instruction on graphing straight lines and also, includes advice on common mistakes made by students.

Here is a site that clearly and thoroughly explains the equation of a line, including how to find points on a line, intercepts, and how to recognize the equation of a line. There are example problems solved, problems for the student to...

This site explains what a linear equation is, general forms of linear equations, how to graph a line using the method of plotting points. The site also details how to find points on the line given the equation, information about the...

The method of graphing to solve a system of linear equations is demonstrated on this site. Students are shown how to graph the lines, then shown how to find the solution.

Students gain the knowledge of how to plot and recognize first degree equations on a graph. The lesson has an overview, materials, procedures, and evaluation techniques.

Use mathematics to determine what is required to beat world champion Usain Bolt in a 200-meter race. This video focuses on systems of equations that are visualized by completing a table of values and looking for a point of intersection...

The Shodor Education Foundation provides this lesson plan to have young scholars practice simple computation that results in them graphing their answers. If they are accurate they will have a straight line. Students use an interactive...

A brief overview of three methods used to graph lines is presented through examples. Slope-intercept, point-slope, and intercept form are demonstrated step-by-step along with a review of the formula for finding the slope of a line.

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...

For this task, students are shown the graphs of two equations, with areas bounded by their lines and intersections shaded in different colors. They are asked to write a system of equations or inequalities for each shaded area and explain...

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...
