Answer:
y = - 8
Step-by-step explanation:
given slope m =
point (5, -2) for (x1, y1)
equation for point slope form
y - y1 = m(x- x1)
y - (-2) = (x -5)
y + 2 = x - 6, simplify
y = - 8,
further you can multiply by 5 to get rid of fraction
5y = 6x - 40
The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:
Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:
Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:
Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:
Answer:
half a slice = 0.55 $
