Question

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

A. (-3,-2)
B. (-2,-3)
C. (0,4)
D. (4,0)

Answer 1

ANSWER

B. (-2,-3)

Step-by-step explanation

The given equation is


`7x - 5y = 1`

We want determine which of the ordered pairs is a solution to the given equation.

For point A(-3,-2)


`7( - 3) - 5( - 2) = 1`


`- 21 + 7 = 1`

This statement is false.

For option B(-2,-3)

We have


`7( - 2) - 5( - 3) = 1`


`- 14 + 15 = 1`


For option C(0,4)

We have


`7(0) - 5(4)=1`


`0 - 20=1`


For option D(4,0)

We have


`7(4) - 5(0)=1`


`28 - 0=1`

This statement is false.
