Big Ideas: A linear function can be written using the formula y=mx+b, slope intercept form. The slope represents the rate of change and the intercept represents the fixed amount. This lesson builds on a student's ability to read a description of a relationship and recognize what each part represents. The task has students compare two plumbing companies to choose the better price based on how many hours they need the plumber. The students must recognize the slope and y-intercept and substitute them into the slope-intercept form to write a linear function. This builds towards being able to recognize linear and other types of functions in a description of a relationship. Vocabulary: Slope, y-intercept, linear function
