1. There were 11 yards mowed. Each yard is represented by an x on the line plot.
2. The most amount of gas used on any one yard was 5/8 of a gallon. The least amount of gas used was 1/8 of a gallon. The difference is (5/8)-(1/8)= (4/8)= 1/2 gallon
9, because one square megameter is equal to one million square kilometers.
Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
