Orgin is the intersection of horizontal and vertical number lines.
the y-axis is the horizontal axis
gridlines
An undefined slope is vertical.
vertical lines run from top to bottom, horizontal lines run from left to right the difference between the two is 90 degrees if you place vertical lines next to horizontal lines.
The answer to this question depends on whether the reflection is in a vertical line or a horizontal line. For example, the reflection of 3 in a horizontal line is 3 but in a vertical line it is E.

The vertical y axis on the Cartesian plane is both negative and positive
a horizontal reflection is a reflection of the y axis. i.e (-fx)
Vertical is up and horizontal is across
Rows are vertical and columns are horizontal.
Vertical and horizontal
with a vertical line: A, M, T, U, V, W with a horizontal line: B, C, D, E, K with horizontal and vertical lines: H, I, X with any line: O
vertical and horizontal
Vertical
No. Up-down is vertical. Horizontal is perpendicular to vertical.
