x = 0 | 0 - 13 = (-13) | (0, -13) x = 1 | 1 - 13 = (-12) | (1, -12) x = 2 | 2 - 13 = (-11) | (2, -11) ---- Common sense says, by plotting the coordinates above in our head, [ x - 13 ] makes a diagonal line. It has a positive slope, as the line rises.

Diagonal means across at an angle, not horizontal or vertical.
Write three numbers whose sum is 10 in all horizontal vertical and diagonal?
Diagonal means a line that is not vertical or horizontal, but in between. i.e. / or \
No. The diagonal through a rectangle can be computed via the Pythagorean theorem: c2 = a2 + b2 where c is the diagonal length and a and b are the horizontal and vertical lengths of the rectangle.
No. A row is horizontal and a column is vertical.
Diagonal means across at an angle, not horizontal or vertical.
Yes. It has vertical, horizontal and diagonal planes of symmetry
It is neither. A diagonal line occupies the range of everything in between those two absolutes.
yes, diagonal to the right and left, horizontal, and vertical.
Skew lines There is a vertical (or horizontal) and a diagonal!
