Hi all,

Is it possible to collect each student’s input data to generate a graph?

For example, generate a graph on slide 2, using the data from this Desmos activity slide 1. [10 26 Starting number & Rate of Change - Activity 2 • Activity by Harry Huang](https://teacher.desmos.com/activitybuilder/custom/5f94c21a2001e00b3e69dc33)

If it works, it may also be possible to plot different lines too?

Does it relate to this command?  
numberList(“N”): aggregate(input.numericValue)

Thank you!

1. You can aggregate separate numeric values. So, to graph values from slide 1, in your slide 2 graph:

```auto
numberList(`X`): aggregate(table1Name.cellNumericValue(1,1))
numberList(`Y`): aggregate(table1Name.cellNumericValue(1,2))

```

In your graph, to graph all the points add in `(X,Y)`.

1. You can plot different lines as well as long as you’re aggregating numeric data (e.g. the slope and y-intercept) and using those to create your equation (i.e. `y=Mx+B).

You could also create a best fit line from your aggregated data from #1 using `Y~mX+b`.

Thank you so much, Daniel, I am excited to try it out ~~~
