Answer:

Step-by-step explanation:
Use the slope-intercept form:

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:


To find the slope, take any two points from the line:

Use the slope formula for when you have two points:

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:


Simplify parentheses (two negatives makes a positive):


Simplify (two negatives make a positive):

The slope is
and the y-intercept is
. Insert these into the equation:

Finito.
F(r) = 3.14r^2....and ur looking for f(5)....so basically all u do is sub in 5 for r.
f(5) = 3.14 * 5^2
f(5) = 3.14 * 25
f(5) = 78.50 <===
To solve this you would add up all the money then divide it by the number of days the guy worked
100+60+150+80+90= 480
480÷5= 96
