A scientist gathers information about the eruptions of Old Faithful, a geyser in Yellowstone National Park. She uses the
data to create a scatter plot. The data show the length of time
between eruptions (interval) and how long the eruption lasts
(duration).
Describe any clusters you see in the scatter plot.

Mathematical Practices

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
