The fractions, numbers, and decimals shown are all slopes.
If the given number is equal to the other, (i.e. slope 7 & slope 7 are equal) then they are parallel.
If the slopes are simply of different values (i.e. slope 5 & slope 6 are intersecting, but should be written as neither.) then they are neither.
If the product of the slopes is -1 ( i.e. [tex]- \frac{1}{2} [/tex] & 2 have a product of -1, so they are perpendicular.) then they are perpendicular.
Now, to the questions.
34. Their product is 1, so they are neither.
35. These are equal, so they are parallel.
36.Their product is -1, so they are perpendicular.
37.Their product is -1, so they are perpendicular.
Hopefully you understand this better. I'll leave it up to you to answer questions 38-51 ;) If you need help, feel free to message me!
