What is the slope of the line that passes through the pair of points?
(-5.5, 6.1), (-2.5, 3.1)

a. -1

b. 1

c. 0

d. undefined

The correct answer is option A.

Step-by-step explanation:

Two points are given ::(-5.5, 6.1), (-2.5, 3.1)

Slope from the two point is determined by the formula :

The slope of the line that passes through the pair of points is -1.

Hence, the correct answer is option A.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
