You can put this solution on YOUR website! Data regarding the value of a particular color copier is represented in the graph. Find the rate of change of the value with respect to time,
(1, 3) and (3, 1)
.
Basically, the two points provided are two points on a graph where the x-axis is time and the y-axis is "value of the color".
.
So, when they are asking for "rate of change of the value with respect to time", they are asking of the slope between the two points.
.
Slope between two points is:
(y2-y1)/(x2-x1)
.
plugging in our two points:
(y2-y1)/(x2-x1)
(1-3)/(3-1) = -2/2 = -1
.
So, -1 is the rate of change.
