What must be true about the average rate of change between any two points on the graph of an increasing function?
if a function is increasing, the average change of rate between any two points must be positive.
How do you find the constant rate of change on graph?
You measure the change in the vertical direction (rise) per unit change in the horizontal direction (run). The rate of change is constant between A and B if AB is a straight line. Take any two points, A = (xa, ya) and B = (xb, yb) then the average rate of change, between A and B = (yb- ya)/(xb- xa).
If you know two points on a line how can you find the rate of change of the variables being graphed?
You divide the difference in y-coordinates by the difference in x-coordinates. Or whatever the variables are.
How do you find rate of change if change is not constant?
Find the derivative
Find the rate of change between the two points (436) and (8108) and the give the unit of measure?
Because of the absence of any separators, it is not possible to tell whether the first point is (4, 36) or 43, 6). Consequently it is not possible to give a proper answer. Since these are both pure numbers, there would be no units to the rate of change.
