ILL MARK BRAINLIEST, ANSWER ASAP

We have to use tho point from the table to get the slope and y-intercept.

(3, 14) and (4, 12)

Slope = (12 - 14) / (4 - 3) = -2 / 1 = -2

Now our equation looks like: y = -2x + b

Let's plug one of our points into the equation.

12 = -2(4) + b

Simplify

12 = -8 + b

Add 8 to both sides.

20 = b

The final answer is: y = -2x + 20

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
