What is the solution to the system of equations graphed below?

 (2, -3)

Step-by-step explanation:

Look at the point where the two graphed lines cross.  

The first number in the solution is the x-value,  that is how far to the left or right you count from the center O.  2 to the right +2

The second number in the solution is the y-value, that is how fat up or down you count from the center O.   3 down is -3

When you have those two values, you express them as the "coordinates" of that point. in this case  (2, -3)

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.
