In the coordinate plane, the x-axis (y=0) and y-axis (x=0) are perpendicular. The product of the slopes of two perpendicular lines is -1. Explain why this definition does not apply to the lines y=0 and x=0

Because the slope of the line x=0 is undefined, and the slope of the line y=0 is 0 and anything times 0 is 0

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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
