PLEASE HELP. It is discovered that the college registration process for Professor Smith's Calculus class can be modeled by the equation y=2x+12, where y = the number of students registered at the end of each day, and x = the day of registration. Professor Smith has 12 students pre-registered before the registration process begins, and the registration closed after 7 days.
