2) Three ways you could mislead a graph is ...

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?
  • Line graph
  • Bar graph
  • Circle graph

2b) I would probably still keep selling pizza subs because i noticed that every week the sales of the pizza keeps going up and up so i think when i keep selling it its going to be fine . the graph explains my answer because in a line graph it shows data over time and in this data it shows that every week it keeps going up

4a) would choose the line graph because Mrs. Mota will notice that the sales keeps going higher and higher so for sure she will keep the healthy foods keep on going .

4b) How to make the graphs look more impresive
