Slope is the change in y (vertical dimension) with the change in x (horizontal dimension). On a Cartesian coordinate system, the slope is equal to infinity for change in x = 0, or a vertical line.
"Landscape" orientation prints the page in such a way that in order to read it, you hold the paper with its longer dimension horizontal and its shorter dimension vertical.
Height or altitude.
The two letters for a 2-dimensional plane are X and Y. Each one is known as an axis, therefore being the X axis and the Y axis. The X axis is the horizontal dimension and the Y axis is the vertical dimension.
Length can be measured either way. The actual definition of length is the longest dimension.A shape that is two units horizontal and three units vertical will have a length of 3, and in this case, the length is measured vertical. At the same time, a shape that is three units horizontal and two units vertical will also have a length of 3, but in this case, the length is measured horizontal.Many people make the mistake of thinking that length is always horizontal or always vertical. This is incorrect, however. The easiest way to see that this is false is to rotate the shape 90 degrees; this causes the length to change to what was before the width, and as such, length is not consistent, even though the shape is the same. Length is always the longest dimension. As such, width is always the dimension that makes a (two-dimensional) right angle with the length. This will always just be the other dimension in two-dimensional objects.
