Give me explanations and answers for numbers 3 and 5.
In Exercises 1–14, use intercepts and a checkpoint to graph each linear function.
In Exercises 9–24, find the equation of each of the circles from the
given information.
Use Graphs A-D for Exercises 9–11. During the winter, the amount of water that flows
down a river remains at a low constant. In the spring, when the snow melts, the flow of
water increases drastically, until it decreases to a steady rate in the summer. The flow
