PLZ HELP-WILL FAN Neil has been running a tutoring business since 2005. He charges a monthly fee for weekly tutoring sessions and a phone help line. Each year, he has increased his fee by the same amount. The table shows what Neil charged each customer for two given years of his business: Year Annual Tutoring Fee 2005 $1200 2008 $1350 A. What is the rate of change and initial value for Neil’s business? How do you know? B. Write an equation in slope-intercept form to represent the fees that Neil charges each year.

    \[1350-1200=150\]\[2008-2005=3\]\[\frac{ 150 }{ 3 } =50\]
