Let's Practice! Quipper Individual Practice: 1. Find the equation of the line containing RS whose perpendicular bisector is -x + 4y = 6 if R lies on (-8,8). 2. The equation of the line containing AC is given by x + 2y = -18, and its perpendicular bisector is -2x + y = -14. Find the coordinates of c if A lies on (-6, -6).Let's Practice! Quipper Individual Practice: 1. Prove that quadrilateral ABCD with vertices A(-4,2), B(3,2), C(4, -3), and D(-3, -3) is a parallelogram by showing that its opposite sides are parallel. 2. ABCD is a parallelogram. Three of its vertices are located at A(2,3). B(9,3), and C(7, -4). Find the coordinates of the fourth vertex D.Let's Practice! Quipper Individual Practice: 2.
