Translating Word Problems into Linear Equations A cell phone company charges $45 a month and $0.25 per minute. Write a linear equation to show the total cost for using the cell phone for a month in slope-intercept form (y = mx + b). 1. Define: y = x = 2. Write the equation: y = mx +b What is the slope? What does this slope mean? What is the y-intercept? The Georgia Aquarium charges $25 per student with a $30 processing fee per group for field trips. Write an equation to show the total cost for a field trip to the Georgia Aquarium. If you were to graph this, where would the line cross the y-axis? 1. Define: y = x = 2. Write the equation: y = mx +b What is the slope? What does this slope mean? What is the y-intercept?
