Use the coordinates of the plotted points to complete the calculation below. pay attention to negative signs.

Check the picture below.

The change in y: -6

The change in x: +2

Step-by-step explanation:

The point A is at (1, 6) this means is at x = 1 and y = 6

The point B is at (3, 0) this means is at x = 3 and y = 0

So from A to B the change in y is:

0 - 6 = -6 ⇒ the change in y is 6 units, and it is negative since the value of y decreases.

and the chanche in x is:

3 - 1 = +2 ⇒ the change in x is 2 units, and it is positive since the value of x increases.

d≈7.07in

step-by-step explanation:

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
