Rate of change, or slope, or rise over run, or ‘m’ is the difference between a pair of y-coordinates over the difference between a pair of x-coordinates.
The formula for rate of change or slope is:
m=(y2-y1) / (x2-x1)
All we have to do is take two pairs of coordinates from the table and solve for the slope (m).
Let’s just choose the first two coordinates: (1, 5) and (2, 5).
m=(5-5) / (2-1)
m=(0)/(1)
m=0
So, the rate of change is 0; there is no rate of change. There is 0 rise per 1 unit of run.
To find how many cupcakes Ling must sell to break even, you will create an equation where the functions are equal.
0.25x + 30 = 1x; then solve the equation for x, the number of cupcakes.
0.25x + 30 = 1x
-0.25x -0.25x
<u>30</u> = <u>0.75x</u>
30 30
x = 40
Ling will need to sell 40 cupcakes.
