The vertices of quadrilateral PQRS are given below. Use the distance and/or slope formulas to determine if PQRS is a parallelogram. Use the diagram as a guide. P(-6,4), Q(-2, 7), R(-1,0), S(-5, -3) S R

Please help anyone please and thank you

5) Determine if the lines are parallel, perpendicular, or neither. Must show work. 15x – 10y = -5 and 3x + 2y= 5 Circle One: Parallel Perpendicular Neither (4 points)

2. Use grid paper. Draw and label a coordinate grid. Plot each ordered pair. Explain how you moved to do this. F(3, 5) G(6, 7) H(9, 2) 1(1, 10) J(7, 0) 3. a) Point A has coordinates (0, 17). What do you know about Point A? b) Point B has coordinates (24, 0). What do you know about Point B? c) What is the location of a point with coordinates (0, 0)? How do you know?
