Conclusion/Results:
a) What is the slope of this graph? (The slope is the change in the y-axis divided the change in the x-axis (rise over run) for a straight line)


b) What is the y-intercept? (The point where a line or curve crosses the y-axis of a graph. In other words: find the y value when x equals 0)


c) What is the equation that describes the relationship shown in the graph? Include the appropriate units in your equation. (Linear, quadratic, exponential, or no relationship)


d) Now, connect all data points since this is a nonlinear relationship. Could a graph recording daily rainfall ever have a negative slope? Why or why not?
