I need a definition for this
constant rate of change when graphing in mathematics and for
Positive and Negative correlation
and also what the pattern is in this
a) 1000, 100, 10, 1
I'll give you a definition for positive and negative correlation.
Correlation is a linear relationship between two variables. Correlation can range from -1.00 through 0 to + 1.00. Zero means an absence of a linear relationship. -1.00 is a perfect negative correlation. +1.00 is a perfect positive correlation. Whether the correlation is negative or positive, the closer it is to -1.00 or +1.00, the stronger it is.
An easy way to think of positive correlation might be: when one goes up, the other goes up. Negative correlation: when one goes up, the other goes down. The closer to 0, the weaker the correlation.
I hope this part will help.
what is the difference between linear and non-linear correlation?
