Answer: Origin=(0,0)

Explanation:

Given points are : (–2, 2), (–4, 4), (2, –2), and (4, –4) .

We can see that for every x,
y=-x

hence, the equation of the line is y=-4x

The point where the line intersects the y-axis has y coordinate as 0.

When we put y=0 in the equation, we get

$0=-x\\\Rightarrow\ x=0$

Hence, The point where the line intersects the y-axis =(0,0) which is origin.
