Question

What is the equation of the line shown?

x + y = 0
x - y = 0
-x - y = 0

Answer 1

The line is y = x

which you need to manipulate into a form above

Answer 2

would it be -x-y=0

Answer 3

no you will have 1 positive and 1 negative pronumeral

Answer 4

-x-y=0 is the same as y=-x , which is wrong

Answer 5

Another hint: You can add or subtract x or y from both sides to "move" x or y.

Answer 6

would it be the second one then?

Answer 7

yes it is indeed the second one.
