Learners first determine the slope-intercept and standard forms of inequalities given graphs, and then determine key features of the graphs.

What's so special about slope? Pupils first match cards with slope and y-intercept to graphs of linear equations. They continue the lesson by matching equations in slope-intercept form to the same graphs.

Predict the year that college costs will double in your state using linear modeling. The first part of this two-part project based learning activity asks young mathematicians to use data from the College Board. They graph the data,...

An upper-level treatment of what is often presented as a basic concept (the right angle of an inscribed circle on the diameter), this activity really elevates the mathematical thought of the learner! Expected to develop formulas...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

Students will connect the centers of snowflakes with a line preferably by applying the point-slope formula.

Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

This site contains a short tutorial on point-slope, slope-intercept, and general form of linear equations. The site has an interactive graph of lines showing how the graph of a line changes when values of the linear equation change.

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...

Students will identify x- and y-intercepts graphically. Students will calculate the slope between 2 points. Students will write the equation of a line in slope-intercept form when given the graph of the line.

In this activity, students explore the equations of lines written in the form: y = mx + b. They move points defining the lines, and view the related changes in the parameters of the equations.

Students will write an equation in slope-intercept form given two points on the line; write an equation in Ax + By = C form given slope and one set of coordinates; and prove lines to be parallel or perpendicular given vertices of...
