A value that does not change is a constant.
"Constant" means that something doesn't change.

A constant that does not change!
Constant is a quantity that does not change.
A "constant"
You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
"Slope" can be thought of as rate of change - and a constant doesn't change.
A linear relationship.
The differentiation of a constant is zero because a constant value does not change with respect to the variable being differentiated. The derivative measures the rate of change of a function, and since a constant has no change, its derivative is zero.
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
