The table below shows the number of cakes Stella baked with respect to time. Number of Cakes Time
(hours)
3 2
6 4
9 6
12 8
15 10

Which of the following statements gives the unit rate?
A.
Stella baked 3 cakes in each hour.
B.
Stella took hours for each cake.
C.
Stella baked 2 cakes in each hour.
D.
Stella took of an hour for each cake.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

ou would have 12 of each
