Find the slope of the line that passes through the pair of points

Step-by-step explanation:

To find the slope from two points you can use the following formula:

Now substitute the two sets of points

Substitute the values like this:

and

Now you will need to simplify the following expression:

Make sure that denominators are the same before substracting:

when you divide with a fractional number you only need to flip the second fraction over (find its reciprocal). Then just multiply:

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.
