Two functions are represented in different ways.

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.

Which statements are true?

Select each correct answer.

Function 1 has a greater rate of change than function 2.

Function 2 has a greater rate of change than function 1.

Function 1 has a greater y-intercept than function 2.

Function 2 has a greater y-intercept than function 1.

Well function two given the information provided would be:

y=10x+25

And since a line of y=mx+b means that it has a slope of m and a y-intercept of b we can say that in comparison to y=20x+15:

Function one has a greater rate of change (slope) than function two (20>10)

Function two has a greater y intercept than function one (25>15)
