13. (-7, -5) and (2, -8)
what is the slope of this ?

the slope is 1/3

Explanation:The slope of this line is

1

3

, and the rise of this slope is

+

1

.

Explanation:

Given two points on a line with coordinates

(

x

1

,

y

1

)

and

(

x

2

,

y

2

)

, the slope of the line,

m

, is found using the formula

m

=

y

2

−

y

x

−

x

1

Since we have two points

(

7

,

−

2

)

and

(

4

,

−

3

)

, we can substitute these coordinates into the slope formula and simplify the expression to obtain the slope of this line.

m

=

−

=

−

=

So the slope of the line is

1

3

.

As for the second question, slope is often defined as "rise over run." Therefore the 'rise' of this slope is

+

1

.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
