The line joining the point $(0,0)$ to the point $(x,y)$ has slope or gradient $y/x$.
The larger the number $y/x$ the steeper the slope.
If $y/x=1$ then the angle of the slope is $45^\circ$.
If $y/x < 1$ then the angle of the slope is less than $45^\circ$.
If $y/x > 1$ then the angle of the slope is greater than $45^\circ$.
