Question 28989
You have three pairs of numbers.  You only need two to
determine a linear equation.
Points are (62,7000), (63,7500), (64,8000)
Using the 1st two you have a slope of [500/1]
Using x=63, y=7000, m=500 use y=mx+b to find "b".
7000=500(63)+b
7000=31500+b
b=-24500
Your equation is y=500x-24500
