If 2 more students took the math test and both made a score of 80. What would the picture graph look like?

To represent the addition of 2 students scoring 80 on a picture graph, you would add two symbols (such as icons or images) next to the existing representation for the score of 80. If there were already symbols representing previous students' scores, you would simply increase the count for that score by two. The overall visual would reflect a total of more students contributing to the score of 80, making it visually larger or more prominent than it was before.
