no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.
a car braking is a negative rate of velocity change
left to right positive,right to left negative rate
well the rate of change is how much something changes in a matter of time, so it can be graphed in a slope because slopes can represent changes ( negative and positive, zero and undefined)
The slope of a linear function is also a measure of how fast the function is increasing or decreasing. The only difference is that the slope of a straight line remains the same throughout the domain of the line.
There are several uses for those; basically any situation where a rate of change is proportional to a quantity. The growth of a population growth under ideal conditions (with a positive exponent) and radioactive decay (with a negative exponent) are common example.There are several uses for those; basically any situation where a rate of change is proportional to a quantity.

A quantity with a negative rate of change becomes smaller as time goes on. A quantity with a positive rate of change becomes larger as time goes on.
left to right positive,right to left negative rate
It can be positive or negative, or even both - at different stages.For example, the rate of change of the balance in my bank account is positive at the end of the month - when my pay goes in - but it is negative for most of the rest of the time while I am spending it!
No
acceration means rate of change of velocity and if that acceration is negative then it is called as retardation
of Accelerate
Acceleration and deceleration are both the rate at which velocity changes, Deceleration is a negative acceleration. In an equation the rate of deceleration is shown as a negative acceleration valueCentripetal acceleration is different and represents the rate of change of tangential velocity. There is no equivalent centripetal deceleration.

0. There is no x in your equation so regardless of how you change your input, the output y never changes.
Deceleration is a special case of what physicists call "acceleration" - a rate of change of velocity.
It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
