A Cartesian coordinate system with x x\,x and y y\,y axes ranging from -5 to 5. The origin is labeled OOO. A line segment connects point P P\,P at (−3,4)(-3, 4)(−3,4) and point Q Q\,Q at (2,−1)(2, -1)(2,−1).
a.[1]
Plot the point with coordinates (4,−2)(4, -2)(4,−2). Label this point RRR.
b.[1]
Write down the coordinates of the midpoint of PQPQPQ.
