Which of the following lines has a slope of - 1/2? my options are x - 2 y = 0 - x + 2 y = 0 x + 2 y = 0

Answer: So x + 2y = 0 is your answer

Step-by-step explanation:

if you look simplify all of these, you will get:

x - 2y = 0

-2y = - x

y = 1/2x No

-x + 2y = 0

2y = x

y = 1/2x No

x + 2y = 0

2y = - x

y = - 1/2x Yes!

So x + 2y = 0 is your answer
