note: enter your answer and show all the steps that you use to solve this problem in the space provided. use the function rule, y = 2.1 +5, to find the values of y when x = 1, 2, 3, and 4. write the answers as ordered pairs that would be used to graph the function.

(7,5)

(9,5)

(11,5)

(13,5)

Step-by-step explanation:

For the first step we plug in x

y=2(1)+5

y=7

y=2(2)+5

y=9

y= 2(3)+5

y=11

y=2(4)+5

y=13

Since the plus 5 is the y intercept we put that in the ordered pair like so:

(7,5)

(9,5)

(11,5)

(13,5)

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
