Salma left her house at time zero and drove to the store, which is 6 blocks away, at a
speed of 3 blocks per minute. Then she stopped and went into the store for 7 minutes.
From there, she drove in the same direction at a speed of 9 blocks per minute until
she got to the bank, which is 18 blocks away from the store. She stopped at the bank
for 2 minutes. Then she drove home at a speed of 2 blocks every minute. Make a
graph of showing the number of blocks away from home that Salma is x minutes
after she leaves her house, until she gets back home.
