Question

Does someone know the answers to question 12 and 13 ??? GIVING 30 POINTS

Answer 1

12. A

13. C

Explanation:

12. to be parallel needs same slope

13. to be perpendicular flip slope and if positive change to negative

Answer 2

Explanation:

For 12 if its a parrell line then the slope of the two lines have to be the same. Since the slope is 3/5 then the answer is A because the slope in A is also 3/5

for 13 if its perpendicular, then the slope has to be the opposite sign and flipped. so for example if its a negative then the slope has to be a positive and if the slope is 1/2 you have to flip it which is 2/1 and 2/1 equals 2.

so in this one if the slope is 3/5 we have to flip it making it 5/3 and the opposite of a positive is a negative so it would be -5/3, so the answer is C.
