Which type of graph would best show the number of markers in each classroom, if markers come in boxes of 20?

The best type of graph to use is a bar graph because bar graphs compare different sets or results to eachother, in this case classrooms.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
