A shorter style of cup is stacked tall.
The graph displays the height of the stack in cm for different numbers of cups.
How much does each cup after the first add to the height of the stack?
Explain how you know.

1) is right

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

15.36 per mile

but forgot to round

i am pretty sure
