HELP PLEASE ASAP!!

1. A table can be a helpful thing to model the rate of change. It can be used by making an x and y column and listing each number underneath it like so:
x y
1 2
2 4
And so on. The rate of change for that table would be every time the x axis goes up 1, the y axis goes up 2.
2. To find the rate of change using a graph, look at the line on the graph. You can make a small triangle that starts on the line and then comes out and re-connects into the line. Like so - (look at attached picture). And as you go, you count how many you go down or up and how many you go left or right.
*Hopefully this was helpful, sorry if t wasn't!

What is the reason for an outlier in a graph?
Anna71 [15]
It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500) while others may indicate that something unusual is happening
