pretty sure it would be 0.075
A good equation would be: f(<em>x</em>)=<em>P</em>(<em>r</em>)^(15). The full equation would be f(<em>x</em>)=<em>P</em>(<em>r</em>/1)^(1(15)), but I just simplified it. <em>P</em> is the initial/principal population of the snails, and <em>r</em> is the yearly rate of growth.
Answer:

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

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run (
).
If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

Now find the slope. Use the slope formula:

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

The slope is 3. Insert this value:
