You start at 11 ,10 and you move 7units left and 5 units down

(4 , 5)

Step-by-step explanation:

Note the point: (x , y) = (11 , 10)

Note that if you are moving left or right, you are changing the x variable.

Note that if you are moving up or down, you are changing the y variable.

In this case, you are starting at (11 , 10)

You move 7 units left (subtract 7 from x):

(11 - 7 , 10) = (4, 10)

You then move 5 units down (subtract 5 from y):

(4 , 10 - 5) = (4 , 5)

(4 , 5) is your answer.

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.
