Question

Two functions are represented in different formats.

Function 1:

Let x = number of hours worked

Let y = total pay in dollars

y = 20x + 15



Function 2: A babysitting club charges a $25 flat rate and $10 for each hour.

Answer 1

function 1 :
y = 20x + 15......rate of change (slope) = 20, y int = 15

function 2 :
y = 10x + 25....rate of change (slope) = 10, y int = 25

function 1 has a greater rate of change then function 2
function 2 has a greater y int then function 1
