Tell wether the slope of the line is positive, negative, zero or undefined

A. Positive
B. Negative
C. Zero
D. Undefined

D. Undefined

Step-by-step explanation:

The line is a vertical line.

Vertical lines have undefined slopes

Undefined

Step-by-step explanation:

Vertical lines will always have undefined slopes. This is a vertical line because it is straight up and down.

To make sure, we can test 2 points: (2,1) and (2,2) in the slope formula

y2-y1/x2-x1

2-1/2-2

1/0

It is impossible to divide by 0, so the slope is undefined.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
