Problem one asks us to make a scatter plot of a graph of data and asks us to determine what type of relationship the scatterplot shows.
00:11
The table that it gives us is the average maximum daily temperature in january for northern latitudes.
00:18
And it gives us a set of latitudes which we put on the x -axis and a set of temperatures which we put on the y -axis.
00:25
The latitudes range from 25 degrees north to 43 degrees north, and so we've spread out the dashes on the scatterplot accordingly, where we start at 25 and at 45, and each dash shown indicates a single degree.
00:47
The temperatures for the y -axis fall between 32 degrees fahrenheit and 76 degrees fahrenheit.
00:59
And so we've made it so that each dash on this grid is 2 degrees fahrenheit.
01:05
So we have 30 to 40, 50, 60, 70, all the way up to 76 in order for this graph to fit within this grid square.
01:14
We then take each x and y point, so we'll start with the first where we are given latitude of 35, so we start here.
01:24
And we're told that there's a temperature of 46 degrees fahrenheit at latitude 35.
01:31
So we just go up to 40, 42, 44, 46, and put a dot there...
