A population of flies grows according to the function p(x) = 6(3)x, where x is measured in weeks. A local spider has set up shop
and consumes flies according to the function s(x) = 4x + 1. What is the population of flies after two weeks with the introduced spider?

Answer:
y=x-2
Step-by-step explanation:
Slope intercept form is a way to describe a function using its slope and y-intercept and is written as y=mx+b.
m=slope
b=y-intercept
Looking at the graph we can see it goes through x=0 at y=-2 making -2 the y-intercept.
Then we must solve for slope, slope is rise/run. From the point (0,-2) the function travels to (7,0).
This gives us a rise (change in x) of 2 and a run (change in y) of 7 and 2/7 as our slope.
