Question

help please

Answer 1

i wanted to know if i got this one correct

Answer 2

hmm ok, so
have you learned about perpendicular slopes before?

like if the slope is 2, then the slope perpendicular to it is the "flipped opposite" like -1/2

Answer 3

oh, ok

Answer 4

i must've forgot.

Answer 5

so in the first and third equation/lines

the slopes are 3/5 and -5/3
which are flipped opposites of each other
which means that when they cross each other, it's going to be a right angle

Answer 6

alright, thank you.
