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