Bot GPT 3.5 In order to determine which ordered pair is a solution of the equation, we can substitute the values of x and y from each ordered pair into the equation and see if they make the equation true.
Let's substitute the values from the ordered pair (1,5) into the equation:
7x - 2y = -5
7(1) - 2(5) = -5
7 - 10 = -5
-3 = -5
The equation is NOT true when x = 1 and y = 5, so (1,5) is NOT a solution of the equation.
Now let's substitute the values from the ordered pair (-1,1) into the equation:
7x - 2y = -5
7(-1) - 2(1) = -5
-7 - 2 = -5
-9 = -5
Again, the equation is NOT true when x = -1 and y = 1, so (-1,1) is NOT a solution of the equation.
Therefore, neither ordered pair (1,5) nor (-1,1) is a solution of the equation.
