As per an axiom in euclidean geometry, if (two, three) points lie in a plane, the (plane, line,) containing those points also lies in the same plan.

Answer is TWO, LINE

If two points lie on the same plane, then the line containing them lies on the same plane. Think of two distinct points on a normal Cartesian coordinate grid. If both points are on the grid, then a line can be drawn between them on the same grid. In this case, the grid itself is the 2-dimensional plane. 

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
