Question

what two types of change are compared to measure steepness?
vertical and horizontal
speed and distance
length and width
depth and height

Explanation:

To measure steepness (like in slope), we compare vertical change (change in y - axis) and horizontal change (change in x - axis). Speed and distance are related to motion, length and width to dimensions of objects, depth and height to vertical/3D measurements, but not for steepness. So the correct option is the one with vertical and horizontal.

Answer:

A. Vertical and horizontal
