Answer:

-6\sqrt{13}

Step-by-step explanation:

This is similar to collecting like terms in Algebra, that is

- 2x - 7x + 3x = x(- 2 - 7 + 3) = - 6x

Similarly

-2\sqrt{13} - 7\sqrt{13} + 3\sqrt{13}

=\sqrt{13}(- 2 - 7 + 3) = - 6\sqrt{13}

The line y = 2 is horizontal where all points on it have a y coordinate of 2.

The vertical and horizontal lines intersect at (6,2)
