Answer 1

Do you mean you want to know which of these have a negative slope?

Answer 2

slope of -1/2!

Answer 3

So you can learn how to do it, what is it you exactly don't understand? :)

Answer 4

Do you know slope-intercept form and standard form?

Answer 5

try to bring every equation in the form of y=mx
by isolating the y
then m is the slope

Answer 6

x + 2y = 0?

Answer 7

first subtract x from both sides, what u get ?

Answer 8

i tried to solve the question and i got x + 2y = 0!

Answer 9

you mean you got slope of -1/2 for x+2y=0 ??
