"Constant" means that something doesn't change.
A linear relationship.
Unit rate, slope, and rate of change are different names for the same thing. Unit rates and slopes (if they are constant) are the same thing as a constant rate of change.
The constant of proportionality is the ration that relates two given values in what is known as a proportinal relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant variation, or even the rate of change.
it is a proportional relationship because a proportional relationship is known as a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
The graph of a relationship in which two variables are in direct proportion is a straight line through the origin, whose slope = the rate of change = the constant of proportionality.
A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
Constants cannot be change during run time, variables can.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
It is a relationship of mutual exclusivity.
No. The relationship between Celsius and Fahrenheit temperatures: C = 5/9*(F-32) is linear. The rate of change is 5/9 F degrees per C degrees but the relationship is not proportional. 0 C is not 0 F.
The value of y increases, such that x*y remains a constant.
A constant rate of change is when a relationship of an equation (y=3x+3) changes to a negative. (y=-x3+3) so now you have one line going like this / and the other going like this \ but crossing each other.
