To create an equation from a table use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1.

To create an equation from a graph choose two points and use LISTS & SPREADSHEET, DATA & STATISTICS, MENU 4, 6, 1. Or, you can also create the equation by using SLOPE-INTERCEPT FORM y = mx + b. Find the slope from RISE/RUN and the Y-INTERCEPT by checking where it crosses the y-axis.
