Look at the picture question and answer in there

x-intercept is for y = 0

y-intercept is for x = 0

We have x - 3y = -9.

Put y = 0 to the equation:

x - 3(0) = -9

x - 0 = -9

x = -9

Put x = 0 to the equation:

9 - 3y = -9

-3y = -9       divide both sides by (-3)

y = 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.
