y-value.
x-value.
rate.
constant of proportionality.

y-value

Step-by-step explanation:

the both numbers together in from of (x,y) is ordered pair. The first number is called the x-coordinate or the x- value and the second number is the  y-coordinate or the y-value.

y-value.

Step-by-step explanation:

correct

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
