y= $3.25x + $5.00
slope intercept form is y=mx+b.
In the word problem, you have $5 as basically your non-negotiable fee, meaning $5 would be your y-intercept (also b).
Then you have 3.25, meaning each game is going to cost $3.25.
so for every game you play, it will cost you $3.25 with a add on fee of $5.00
