Question 353049
Your math teacher found a pattern in how long students study versus their percentage grade on the math tests! She recorded the information below. 
#of hours studied (x) | o.5| 1 | 2 | 2.5 | 3 | 3.5 |
% Test Score      (y) | 65 | ? | 80| ? | 90| ? 
What is the Rule that relates to x and y? 
-----
Just using the three x,y pairs that are given,
y = 10x + 60
---
So f(1) = 70
f(2.5) = 85
f(3.5) = 95
