Two functions are represented in different formats.
Function 1:

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.

Answer 1

Could I help you?

Answer 2

yes please

Answer 3

Of course.
With my pleasure!

That is the function of the first relation y = 20x + 15
right?

Answer 4

right

Answer 5

Great...
Can you find out the equation of the second relation?

Hint:
- $25 flat rate: is the y-intercept (b)
- $10 for each hour: the slope (m)
