The sum of two numbers is 10. The larger number is 4 times the smaller number. What are the two numbers? Original system: x + y = 10, y = 4x Slope-intercept form: y = –x + 10, y = 4x Use the work shown to complete the statement. The slopes and y-intercepts of the two equations are , so this system has
