Point c is the midpoint of ab for a(1,-2) and b(7,2). what is the length of ac? round to the nearest tenth.

Your answer should be “b” i truly hope i could ! good luck (:

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
