Is the ration of x to y the slope ?

here is a good explanation

Step-by-step explanation:

Slope angle values range in degrees from 0 to 90. This way of specifying slope is based on the fact that the slope ratio (y/x) is the trigonometric tangent of the slope angle. Consequently, the slope angle is the inverse tangent (tan-1) of the slope ratio (the angle whose tangent is the slope ratio).
