C ?

Answer 5

not quiteee...

Answer 6

A.

Answer 7

i dont think its b

Answer 8

okay so let's saayy... we have perpendicular lines and we are told
\[m_1 = 2 , m_2 = -\frac{ 1 }{ 2 }\]

focussing on m_1 = 2
what is the reciprocal of 2?

Answer 9

I dont know nothing about reciprocals 1 ?

Answer 10

reciprocal means to flip the number basically..
m = 2 = 2/1 right?
the reciprocal will be 1/2 because we flipped 2/1
makes sense?

but notice how m_2 = -1/2 ?
isn't this negative of the reciprocal of m_1 = 2?

Answer 11

yes

Answer 12

yep..
so, what would the answer be?

Answer 13

negative

Answer 14
