Question

give the coordinate of two points on the line for y=-2

Answer 1

Well, it looks like this:



So all the points would have a y-coordinate of -2.
So for example, (-2, -2) or (4, -2)
As you can see on the graph, basically ANY point with the y-coordinate -2 will work, so just chose another x-coordinate to go with it!

Hope this helped!
