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.

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.

Kaleigh Atkins · Answer 1

For any function y = mx+b, m is rate of change and, b is the y intercept

]Function 1 is

y = 20x + 15,

where rate of change = 20 and y intercept = 15

And for function 2, we can write the function as y = 10x + 25

rate of change = 10 and y intercept = 25

So the statements which are true are

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

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