Graphing linear functions word problems

The  exercise appears under the 8th grade (U.S.) Math Mission and Algebra I Math Mission. This exercise interprets word-problems and imposes them onto graphs.

Types of Problems
There is one type of problem in this exercise:


 * 1) Use the description to graph the line: This problem provides a context-driven problem that can be modeled by a line. The student is expected to read and understand the problem, then use the given information to create the graph of the line on the grid provided.Glfwp1.png

Strategies
Knowledge of graphing lines and an ability to confidently work with word problems are encouraged to ensure success on this exercise.
 * 1) The given information may give indicators of one of the intercepts which can help get one point graphed immediately.
 * 2) The rate of change on a linear problem is the slope.

Real-life Applications

 * 1) The problems in this exercise are applications, creating graphs from story problems.
 * 2) The slope, or rate of change, is a very early derivative which is useful in calculus.
