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

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

.

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

+

1

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
