The graph represents the amount of rainfall, shown by a rain measuring device, over time as a storm is subsiding. What is the rate that the rain is falling?

Answer 1

To determine the rate at which the rain is falling from the graph, we need to calculate the slope of the graph. The slope of a graph represents the rate of change of the dependent variable (amount of rainfall) with respect to the independent variable (time).

To calculate the slope, we select two points on the graph and divide the change in the amount of rainfall by the corresponding change in time.

Let's choose two points on the graph:

Point A: (Time = t1, Rainfall = r1)
Point B: (Time = t2, Rainfall = r2)

The slope (rate at which the rain is falling) is given by:

Slope = (r2 - r1) / (t2 - t1)

By finding two points on the graph and knowing the corresponding values for time and rainfall, you can calculate the rate at which the rain is falling.
