A rock is rolled down a 300-foot steep incline. After 1 second, the rock is traveling 26 feet per second. After 2 seconds, the rock is traveling 52 feet per second. Assume the relationship between time, t, and speed, s, is linear. Write an equation in slope-intercept form describing this relationship. Use ordered pairs of the form (time, speed).
