Line segment ab has a length of 4 units its translated 1 unit to the right on a coordinate plane to obtain line segment a'b what is the length of a'b a: 1 unit b: 4 units c: 5 units d: 6 units

C: 5 units which it you

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
