Help me solve the slope

-3

Step-by-step explanation:

We can find the slope using

m = (y2-y1)/(x2-x1)

    = (2-5)/(4-3)

    = -3/1

   = -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.
