Question

Which table is a justification for the given solution to the system of equations?

( 2, −1 )

{ y=4x−9 y=2x−5

Answer 1

The answer is table B

good luck!

Answer 2

Table B

Explanation:

We are given the following equations

`y_(1) =4x-9\\y_(2) =2x-5\\`

we can plug the different values of
`x` into above equations and get the corresponding values of
`y_(1)` and
`y_(2)`

We need to check that the solution
`(2,-1)=(x,y)` corresponds to which table given in the image below.

We can plug the value of
`x=2` into the equations and get the answer.

`y_(1) =4(2)-9=8-9=-1\\y_(2) =2(2)-5=4-5=-1\\`

Hence we can clearly see that our values match with the table B (right side top one)
