The school band is putting on a concert. eight students signed up to play the trumpet, 8 students signed up to play the flute, and 8 students signed up to play the violin. which circle graph could be used to display the data?

The circle graph that can best display the data is called a pie chart. The pie chart shows the given data as part of a whole and indicates its percentage as well. In this case, the pie chart will be divided into three - those students who signed to play the trumpet, flute, and violin. 

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
