7. Which of the following is an
equation of the line through
(11, -3) and (7, 9)?

Step-by-step explanation:

which is (y2-y1)/(x2-x1)

= 9-11 / 7- -3

= -2/10

gradient = -1/5

which is (x1 + x2)/2 , (y1+y2) / 2

= 11+7 = 18/2 = 9

= -3 + 9 = 6/2 = 3

midpoint = (9,3)

now create the equation using the formula

Y1 - y = m(x1 - x)

where m is the gradient

now place the midpoint values in the equation

y- 3 = -1/5 (x-9)

y - 3 = -1/5x +9/5

y=-1/5x + 9/5 +3

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.

x = 3 ± √(5+y)
