Two cars are traveling from NYC to Miami. Car A's trip can be modeled by the equation y = 60x + 50 miles per hour. Car B's trip can be modeled by the table.
If the cars leave at the same time, which car will get to Miami first? How do you know?
If the cars leave at the same time, which car will get to Miami first? How do you know?
Car A will reach Miami first because car A is traveling at a faster rate.
