Question three (1 point)

3) Which ordered pair in the form (x, y) is a solution of this equation?
7x - 5y = 1

A. (-3, -2)

B. (-2, -3)

C. (0,4)

D. (4,0)

Respuesta :

Answer:

B. [tex](-2,-3)[/tex]

Step-by-step explanation:

we know that

If a ordered pair is a solution of  a linear equation. then the ordered pair must satisfy the linear equation

In this problem we have

[tex]7x-5y=1[/tex]

verify each case

case A) [tex](-3,-2)[/tex]

substitute the value of x and the value of y in the linear equation and then compare

[tex]7(-3)-5(-2)=1[/tex]

[tex]-11=1[/tex] -----> is not true

therefore

The ordered pair case A) is not a solution

case B) [tex](-2,-3)[/tex]

substitute the value of x and the value of y in the linear equation and then compare

[tex]7(-2)-5(-3)=1[/tex]

[tex]1=1[/tex] -----> is true

therefore

The ordered pair case B) is a solution

case C) [tex](0,4)[/tex]

substitute the value of x and the value of y in the linear equation and then compare

[tex]7(0)-5(4)=1[/tex]

[tex]-20=1[/tex] -----> is not true

therefore

The ordered pair case C) is not a solution

case D) [tex](4,0)[/tex]

substitute the value of x and the value of y in the linear equation and then compare

[tex]7(4)-5(0)=1[/tex]

[tex]28=1[/tex] -----> is not true

therefore

The ordered pair case D) is not a solution
