# Math

Hey, I need your help! I have an input output table that I need the function rule for. The table is like this:
Input: 0 Output: 25
Input: 100 Output: 35
Input: 200 Output: 45
Input: 300 Output: 55
Input: 400 Output: 65

1. try linear
y = m x + b
35 = m (100) + b
65 = m(400) + b
-----------------
-30 = -300 m
m = 1/10

35 = 10 + b
b = 25

so I think
y = 0.1 x + 25
or
10 y = x + 250
try that
