Which ordered pairs are on the line 3x−4y=9 select each correct answer

see explanation

Step-by-step explanation:

to determine which of the ordered pairs are on the line, substitute the coordinates of the point into the left side of the equation and if the value obtained equals the right side then it lies on the line.

(, - )

2 + 7 = 9 ⇒ correct

(- 5, - 6 )

- 15 + 24 = 9 ⇒ correct

(1, - )

3 + 6 = 9 ⇒ correct

(- 1, 3 )

- 3 - 12 = - 15 ⇒ incorrect

The 3 ordered pairs

( , - ), (- 5, - 6), (1, - )

All line on the line 3x - 4y = 9

i can answer this question sweetie!

step-by-step explanation:

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.
