The equation below can be used to model the approximate cost of different numbers of carnival passes.
cost = 10 + 8p
which of the following is true?
a. the slope is 8 and represents the cost of eight passes.
b. the slope is 10 and represents the cost of 10 passes.
c. the slope is 8 and represents the change in cost for each additional pass.
d. the slope is 10 and represents the change in cost for each additional pass.

Slope-Intercept form is in the format of y=mx+b, where m is the slope and b is the y-intercept. Therefore, we can rewrite the given equation dollarsas Cost=8p+10.

We can eliminate B and D because they mention that 10 is the slope, when the true slope is 8.

A.) is the correct answer because each pass is equal to 8 dollars (dollars is an assumed unit, it could be anything though).

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
