Name: ___________________________________Date: ____________________Period:_______________ Final Exam Review # 2: Linear Due: May 17th, 2013 1. The equation, y = 20 – 4x, gives the amount of water in the pool after x minutes. Graph the equation. Find its intercepts. Describe the meaning of the y-intercept. What is the slope of the line? Label and scale both axes on the provided graph accurately. x-intercept: __________ y-intercept: _________ Meaning of y- intercept: _________________________________________ Julie is running a 5-kilometer race. She ran one kilometer every 6 minutes. Julie’s distance from the 1 finish line after x minutes is represented by the equation: y = 5 - x. Find the x-intercept and describe its 6 meaning. 2. Meaning of x-intercept: ______________ Meaning of y-intercept: _________________________ 3.
