Plug in some numbers into 1/2 x, and see if those coordinate pairs match up with one of those lines... :3

anonymous · Answer

Ok, but how does that help me find out which line is the answer?

anonymous · Answer

To start with, let's plug in -1, 0, and 1 into 1/2 x. What are your coordinate pair answers? :)

anonymous · Answer

So take 1/2 and times it by -1 and 0?

anonymous · Answer

Whn i took 1/2*-1 i got 0.5 then 0 with the other

anonymous · Answer

For -1, you should get (-1, -0.5) and for 0, you should have (0,0)
Which line passes through those two points? :)

hero · Answer

Write as y = x/2

In this way, it is easy to see that at every point, y is always HALF of x

anonymous · Answer

@anitasonia98 It would be c?

anonymous · Answer

Yup. Nice job! :)
