your local rollerblade rink will rent you blades for $14.00 for 3 hours or $29.00 for 8 hours. Asume the price increase is constant depending on the number of hours the blades are rented.
Find the expression

algebra 
Damon,
x = hours
y = price
two points (3,14) and (8,29)
y = m x + b
m = (2914)/(83) = 15/5 = 5
y = 5 x + b
14 = 5(3) + b
b = 1
so
y = 5 x  1 
algebra 
logan,
hey damon..thank you for your answer but would 15/5=3...so where would the 3 go...thank you

algebra 
Damon,
whoops, sorry
m = (2914)/(83) = 15/5 = 3
y = 3 x + b
14 = 3(3) + b
b = 5
so
y = 3 x +5
