In this exercise, students practice determining the linear equation and slope from two points on a line graph. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

In this exercise, students practice constructing the linear equation given two points on a line graph. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

This collection of five middle school math lessons covers the topic of plane geometry, specifically the concept of slope. The first lesson introduces students to plotting points on a Cartesian grid using a Geoboard. Lesson two moves them...

This graphing game challenges players to supply the coordinates for points shown on a series of graphs and also to plot pairs of coordinates on simple Cartesian planes.

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.

This site answers many general questions about linear equations and their graphs. A student posed several questions to Dr. Math regarding lines and their equations. Question number 4 is about the equation of a horizontal line and Dr....

This one page website lets you practice plotting points on the coordinate grid. See if you can find the missing coordinates to complete the shapes. When you are finished the solutions are only a click away.

This study guide on lines in a coordinate plane covers key terms, what different line slopes look like, postulates about parallel and perpendicular lines, the slope-intercept equation, how to graph parallel and perpendicular lines, and...

Solve a number riddle by finding the point of intersection for two lines. This video focuses on finding the solution for a system of equations, they are represented as an algebraic expression and a set of linear equations that are...

On this one page website sharpen your logic, graphing and pattern recognition skills while working on this challenge. The solution is available to double check your solution.

Practice solving word problems by interpreting the meaning of points plotted on an xy coordinate system. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The purpose of this task is to introduce students to systems of equations. It takes skills and concepts that students know up to this point, such as writing the equation of a given line, and uses it to introduce the idea that the...

In this task, 8th graders are shown the graphs of two lines with the same slope. They are given the equation for the first line and the coordinates of a point on the second and are asked to find the equation for the second line. Aligns...

This interactive media source has two parts a learning mode and a practice game mode. The learning mode is where students are guided through understanding concepts of linear functions. Next, students play a game where they are asked...

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

Not only does this site show what the slope-intercept form is, but it helps you find the slope and the intercept of a line. There is also additional information on parallel lines, parametric form, and the distance between two points.

This site from the Northeast Parallel Architectures Center, Syracuse University has a very substantial discussion of math topics slope & line equations. The outline form is quite useful if you need to zero in on one aspect of...

The handout investigates the calculus concept that given a section of a smooth curve, there is at least one point on that section where the slope of the curve is the same as the average derivative. The exercise consists of a graph that...
