Unformatted text preview: In general, the graph of x y= is a _____________________ over the x axis of the graph of x y = . 3) 2 1+= x y Absolute value equations can be used to model time and distance problems. To make things easier, we sometimes consider the time before an event to be negative. We will consider time before arrival to be negative in the next problem. 4) Suppose you pass NIST half way along your tip to school each morning. You walk at a rate of one city block per minute.
