Answer 3

Step 1) record the x coordinate of each point. This is because the variable A is along the x axis

Step 2) Add up those x coordinates you wrote down in step 1

Step 3) Divide the result in step 2 by 10 because there are 10 points, so there are 10 x coordinates recorded in step 1 and added up in step 2
