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)

Answers

Answer 1
Answer:

The ordered pair is (-2, -3)

Step-by-step explanation:

  • Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.

(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1

(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1

(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1

(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1

So the ordered pair is (-2, -3)
