The ordered pairs (x,y) show the amounts y of inches of rainfall equivalent that are equivalent to x inches of snow.
(16, 1.5), (12, 1.3), (18, 1.8),
(15, 1.5), (20, 2.1), (23, 2.4)
We can represent the data set in a table.

We want to find how many inches of rainfall is equivalent to 6 inches of snow. To do so, we will graph a line of fit. Let's start by making a scatter plot with the given data points.
Now we will draw a line that is close to the points.
To find how many inches of rainfall is equivalent to 6 inches of snow, we can make a vertical line x = 6. Then, we can mark the point of intersection of the vertical line and the trend line. The y-intercept of this point is the amount of rainfall that is equivalent to 6 inches of snow.
We found that 6 inches of snow is equivalent to about 0.6 inches of rainfall.
