I don't see the table in your message. Please paste the kindergarten–3rd grade words-per-minute values so I can write the exact function.
If you want the method now: treat grade as x (use x = 0 for kindergarten, x = 1 for 1st grade, x = 2 for 2nd, x = 3 for 3rd). If the table gives two values (x1,y1) and (x2,y2), compute slope m = (y2 − y1)/(x2 − x1), then use y − y1 = m(x − x1) to get y = mx + b.
Example: if the table were K=40, 1st=60, 2nd=80, 3rd=100 then m = 20 and b = 40, so y = 20x + 40. Paste your actual numbers and I’ll give the exact function.
