PLEASE HELP 20 points A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.

Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Part C: If the rate at which the candle burned was 0.4 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)

A) Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour it started burning.

Equation to find ordered pairs; if x= hours and y= inches then F(x)= 9-x(0.5) so

(1)(1,8.5)

(2)(2,8.0)

(3)(3,7.5)

(4)(4,7.0)

(5)(5,6.5)

(6)(6,6.0)

  (B) Is this relation a function? Yes this is a linear function because the equation is linear, when plotted the line is straight with a negative slope.

(C) If F(x)= 9-x(0.5) Then

(1)(1,8.65)

(2)(2,8.20)

(3)(3,7.75)

(4)(4,7.30)

(5)(5,6.85)

(6)(6,6.40)

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
