You can put this solution on YOUR website! Question:
What is the equation for these (x, y) pairs?
(-4,4),(-2,2),(-1,1),(1,1),(3,3)
---
the data points you gave are not linear, that is to say, the x,y pairs you gave do not fall on a single line, but rather are spread out.
---
the proper way to get a line from your data points is to do a linear regression over them. you can do that here:

---
input your data points into the above tool, using a list like so:
-4, 4, -2, 2, -1, 1, 1, 1, 3, 3
---
now click the Graph button on that tool. you will get a linear regression for your data points.
---
that linear regression is:
y = (-0.15068493150684933)x + 2.1095890410958904
