Answer:
Step-by-step explanation:
We will use the point slope formula: 
We will start by finding the slope(
).
The formula for slope is
So if we just choose 2 random points on the line:
I choose (0,2) and (4,1), we get:
That's our slope.
Next we need to find the y-intercept(
). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.
So in point-slope form the equation is:
The "mean" is the same thing as the "average".
To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.
If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.
If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.
