You have to know how to enter this into your calculator. Step by step: hit the stat button and then edit. Enter your x values one at a time in the first column, hitting enter after each value. When finished with x's, arrow over to the second column and enter each y value in, one at a time, hitting enter after each value. When you're done, hit stat again, tab over to calc and hit enter. You will then arrow down to LinReg(ax+b). Hit enter. If you have a TI 83, then the equation should just generate automatically. If you have a TI84 family, you need to arrow down to "calculate" and then hit enter. Your equation will then generate. It is the last choice above, y = 1/2x + 4.
