On a TI-84, what is the correct sequence of keypresses to enter paired x,y data into lists L1 and L2 starting from the home screen?

STAT → CALC → QuadReg, and then type in x and y values into the function prompts directly; editing L1 and L2 is unnecessary because QuadReg populates lists automatically.

2nd → TRACE → press ENTER repeatedly to open a graph, then type each ordered pair separated by commas into the Y= editor, which automatically populates L1 and L2 when you press GRAPH.

STAT → EDIT → enter x-values in L1 and y-values in L2 (typing each then pressing ENTER), which stores paired data ready for regression.

MODE → select DATA mode → use the VARS menu to choose L1 and L2 and paste data directly from clipboard; this is the only reliable method for entering paired data.
