Write an equation of the line that passes through the points 0, -1 and 2,3

Use the two point formula: y-y¹/x-x¹ = y²-y¹/x²-x¹ to find the equation of a line through two given points.

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.
