the speed at which a variable changes over a specific period of time
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
It means express the slope along with its measurement units.
A constant variable is one that is not the independent variable (the one you are changing) or the dependent variable (the one you change). Constant variables are so named because in order for the experiment to be legitimate, it is expected that the scientist control them, thus keeping them constant across all trials. This ensures that changes in the dependent variable are only the result of changes in the independent variable.
yes
It means something that doesn't change, like a number.
Slope in algebra refers to the rate of change of a function at a given point. This can be used in physics, where on a graph that shows the change in velocity, the value of the slope is equal to the acceleration at that moment in time.
For continuous functions, yes.
The change in y over the change in x
yes

Invariably means constant and not prone to change, and can mean always.
