i need help with all of this . i dont understand it

1. y = -1/2x + 1

2. 3x + y =5

3. 12= 2x -3y

4. x + 1/4y = 1

  

write an equation in point slope form for each line according to the givin information show your work.

 

5. containing (-1, -4) and parallel to y= 3x + 2 __________________________________________________________________________________________

 

6. copntaining (2, -4) and parallel to x – 2y = 5 ________________________________________________

 

7.containing (-2, 3) and parallel to x=1 _________________________________________________________

8. containg (4, 15)  and parallel to -x + 2/3y =6 ___________________________________________________

 

9. containing (-1, -6) and parallel to y= -1 ______________________________________________

 

10. y = 2x – 3

11. 1/3x – y = 1

12. 12= 3x + 4y

13. 3x + 6y = 15

14. y = -4

15. x= 1/3

 

16. containing (2,3) and perpendicular to y = 2x -1

17. containing (1, -3) and perpendicular to y= -3

18. containing (3,4) and perpendicular to 2x – 3y = -6

19. containing (4,1) and perpendicular to 1/2x + y =3

20. containing ( -1, 6) and perpendicular to x = -1
