1) 3 = 11, 4 = 15, 5=19

2) Yes, on a graph is creates a linear line. (see attachment)

3) y=2x + 7

4)(other attachment)

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.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
