I would like the students to enter 3 or 4 points like this in an input (1,1),(2,2),(3,3),(4,4). I know how to do this with a table but not from a single input.

# Graph multiple points in a graph from an input

I think this is what you are looking for: Multiple Ordered Pairs from Single Input • Activity Builder by Desmos

You need to capture the values from the expression input, and then create a numberList that keeps the history. I also used parseOrderedPair so the input is read as an ordered pair.

Hey, Craig: thanks for posting “Multiple Ordered Pairs from Single Input”. I’m using your layout, but can only get one ordered pair input to graph, not multiple ones. I’ve tried separating with a comma, space, and no space. Only a single point will plot. Any suggestions?

Thanks,

Andy

Never mind. Got it. Just have to submit them one at a time. Sorry for the bother.
