John earned 100 points the day that he shot a total of 60 free throws and three-pointers combined. Let x = free throws and y = three-pointers. How many of each shot did he make?

What the heck i didn’t know

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
