Answer:
y=65x
f(x)=65x
Explanation:
Let x be time and y be trees planted.
Using the generic equation y=mx+b we can assume "Trees planted=slope x Time+y intercept.
We find the slope, 65, by using the formula m=y2-y2/x2-x1.
m=325-130/5-2
m=195/3
m=65.
Now, to find the y-intercept, let's replace the known variables with unknown ones.
130=65(2)+b
130=130+b
130-130=b
b=0
The result is y=65x.
In function notation, f(x)=65x.
