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.

This exercise is an opportunity for algebra learners to understand the connection between the slope of a line and points found on the line. Use similar triangles to explain why slope m is the same between any two points. Discuss with the...

The idea in the resource is to understand the connections between proportional relationships, lines, and linear equations. To stay within the context of the standard, skip the part of the resource that solves with unit rates. Instead,...

Your learners will explore linear functions by analyzing a graph of the linear equations.Then learners analyze through calculating f(x+P) and g(x+p)

Your algebra learners explore linear functions concretely using tables of values in a collaborative task. The idea that linear function values change by equal differences over equal intervals, is emphasized. The slope and...

The resource is a good introduction to what makes a proportional relationship between two lines. Discuss the similarities of both lines and the possibility of intersection. Use this opportunity to list other acceptable forms of each...

Learners explore linear functions concretely using tables of values in a cooperative task. The concept of the values of linear functions changing by equal differences over equal intervals of one is emphasized. Learners will discover...

What would your dream house look like? A cottage? A medieval castle? High schoolers enrolled in Algebra design the perfect house while using slopes to write equations for various aspects of the project.

The intent of this resource is to show algebra learners that there is a proportional relationship between two lines that have an intersecting point. As the coordinate x increases by a constant, the y coordinate also increases.  It...

Given the least squares regression line, interpret the slope and intercept in the context of the relationship between texting and GPA. Although this task is short and looks simple, some subtle points can be brought to light in a...

Facilitate an understanding of equality using a modeling task. After watching different-sized cups being stacked, learners use their math skills to determine when the height of each cup tower will be the same. Meant as an introduction to...

Your algebra learners write linear, exponential, and quadratic equations containing the same two graph points in this collaborative task.

Many organizations put on barbecues in order to make money. In a real-world math problem, the money allotted to purchase steak and chicken at this barbecue is only one hundred dollars. It is up to your potential chefs to figure out how...

Learners find the common point of a linear and quadratic system given a graph of the system. Then they find a specific point located only on the parabola.

This site from the Columbia University in the City of New York provides brief information on the slope-intercept form, and then has four helpful examples on the subject. Each example goes through the steps involved and arrives at a...

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.

Students can use the x- and y-intercepts to find the equations of lines and create a line design using the slope-intercept form and the limited domain of the segment.

This partner activity is designed to have pre-Algebra students or Algebra 1 students compare and contrast different screen shots and begin to develop concepts needed to describe slope and intercepts.

This Learn Check file is a review of linear equations. There are problems about slope, x- and y-intercepts, and writing equations of lines.

In this activity, students' will use a force sensor to measure the weight of a water filled funnel as it drains. They analyze the weight versus time data and describe it using concepts of slope and intercepts of a linear function.

An introduction to functions with two variables, including several examples relating to linear programming. The tutorial includes graphical examples of the functions and also review questions located at the bottom of the page.
