Write an equation of the line that passes through the given point and is perpendicular to the graph of the given equation. SHOW ALL STEPS PLEASE HURRY I'M BEING TIMED 1.(2, -1); y = -2x + 1

2.(5, 7); y =1/3x + 2

3.(3, -6); x + y = -4

4.(-9, 3); 3x + y = 5

5.(-8, 3); y+4 = -2/3 (x - 2)

6.(0, -5); x - 6y = -2
CAN SOMEONE PLEASE ANSWER THE QUESTION PLEASE
