Rate of change is used to mathematically describe the percentage change in value over a defined period of time. (I looked that up)
So the rate of change is the slope and slope is the ratio of change between any 2 points on a line.
Slope measures the steepness of a line.
Slope is the ratio of the vertical change, called the rise, to the horizontal change called the run between any 2 points on the line.
Slope is written as a fraction in simplest form. 5/10=1/2
Variable for slope: M.
Reply for any more questions, also sorry for a slow response. I thought a lot.
