Q. Which ordered pair is a solution of the equation?−x−4y=−10Choose 1 answer:(A) Only (3,2)(B) Only (−3,3)(C) Both (3,2) and (−3,3)(D) Neither
Equation and Ordered Pairs: Understand the equation and the format of the ordered pairs.The equation given is in standard form: −x−4y=−10. An ordered pair (x,y) is a solution to this equation if, when x and y are substituted into the equation, the equation is satisfied (both sides are equal).
Testing 3,2: Test the ordered pair 3,2 in the equation.Substitute x=3 and y=2 into the equation: \$-x - \(4\)y = \(-10\)\$.\(\newline\)Calculation: \$\(-3\) - \(4\)(\(2\)) = \(-3\) - \(8\) = \(-11\)\$.\(\newline\)Check if the left side equals the right side: \$\(-11\) \neq \(-10\)\$.
Result for \((3, 2)\): Since \(-11\) does not equal \(-10\), the ordered pair \((3, 2)\) is not a solution to the equation.
Testing \( (-3, 3) \): Test the ordered pair \( (-3, 3) \) in the equation.\(\newline\)Substitute \( x = -3 \) and \( y = 3 \) into the equation: \( -x - 4y = -10 \).\(\newline\)Calculation: \( -(-3) - 4(3) = 3 - 12 = -9 \).\(\newline\)Check if the left side equals the right side: \( -9 \neq -10 \).
Result for \((-3, 3)\): Since \(-9\) does not equal \(-10\), the ordered pair \((-3, 3)\) is not a solution to the equation.
