David investigated the correlation between algebra test results and trigonometry test results of his class. He found there to be a strong positive correlation. He then
concluded that in order for a student to do well in trigonometry, they must first be good
at algebra. Is David correct? Justify your answer.

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
