Question

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

Answer 1

ANSWER

B. (-2,-3)

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.
