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

Answer:

Table B

Step-by-step 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)

Answer 2

Answer:

The answer is table B

good luck!
