The scatter plot shows a fairly linear relationship between population and water usage

● The LSRL lowers the sum of the vertical distance between all of the data points and the line of best fit to show the line that represents the relationship between the two variables

● The y means where the data points starts, in this case it is above zero because no one is using less than a certain amount of water per day, the slope shown how high the data goes and how fast, in this case it shows a positive relationship

● the r and r squared values tell me whether or not it is a valid relationship between the two variables to prove legitimacy, in this case it is 6.5, a valid argument.

● The more people there are in a city means that there are more families, more families lead to more people leading to more water use. The r2 being a 6.5 means that there is a positive relationship

● In my household we usually have water saving tactics such as not showering on certain days and only running the dishwasher at night. The fact that we also don't have a yard speaks to how we dont have to use several more gallons watering one

● The more people there are, the more water needs to be used, as more water is necessary to be used in extra dishes, food, and life activities that it is natural for more people to need more water.

● We could use this data to use as a marker that more people means more water, however wo would need to be more specific in how we see how much water a person uses and how much they use in a school setting vs at their homes

● However for our State+city we can use the examples from the variety of cities and their sizes to determine how much water they would use

● Using Sonoma county as a comparison as it has a similar population as sacramento as of the 2010 census, the water result will be 32512.93 gallons for sacramento

● I would say this estimate is reasonable, however some variables that could affect water could be drought, fires, and cost of living rising.
