Q. ind Endpoint from Midpoint and EndpointScore: 0/5Penalty: noneQuestionWatch VideoShow ExamplesThe midpoint of AB is M(0,2). If the coordinates of A are (1,3), what are the coordinates of B ?Answer Attempt 1 out of 2□Submit Answer
Midpoint formula: Midpoint formula: M=(2x1+x2,2y1+y2). We know M(0,2) and A(1,3).
Let B's coordinates: Let B's coordinates be (x,y). We have 0=21+x and 2=23+y.
Solve for x: Solve for x: 0=21+x implies 0=1+x, so x=−1.
Solve for y: Solve for y: 2=23+y implies 4=3+y, so y=1.
