Can you answer 19 and 20 if you can??? thank u

19) A 20) C

Step-by-step explanation:

19. since the lines are parallel, the line will have the same slope. Then you can just plug in the coordinates to find the rest of the equation, so you get y=-2x+6.

20. Perpendicular lines have slopes that are the opposite reciprocals of each other. Since the slope was 1/5, the slope of the perpendicular line would be -5. Now you can plug the coordinates into the equation to solve for b, and you would get y=-5x+12
