The line cuts the X axis at 
and is parallel to the Y axis.
Thus the equation of the line is $\boxed{x=3}$
None of them will get into a negative number. When you have like "2x" is the number twice, right? Some number has to be negative
By definition, we have to:
In plane geometry, a rectangle is a parallelogram whose four sides are at right angles to each other. Opposite sides have the same length.
There is a proof that a quadrilateral is a rectangle:
1) Its parallel sides are the same.
2) Its two diagonals are the same, and they bisect each other at the common midpoint
3) Any rectangle can be inscribed in a circle, two of whose diameters coincide with the diagonals of the rectangle.
4) If all the angles of a quadrilateral are right angles, then it is a rectangle
i got this question too as my homework it so hard ill let you know if i find out the answer.
