Chapter 8: Q2. (page 407)

Tell whether the ordered pair is a solution of $3 x + 2 y = - 8$ .
$(- 2, - 1)$

Short Answer

Expert verified

The ordered pair $(- 2, - 1)$ is a solution for the given equation.

Step by step solution

Step 1. Given Information.

An equation: $3 x + 2 y = - 8$

Step 2. Calculation.

To check whether the ordered pair $(- 2, - 1)$ is a solution for the given equation or not, we will substitute coordinates of point $(- 2, - 1)$ in our given equation as shown below:

$\begin{matrix} 3 x + 2 y = - 8 (Givenequation) \\ 3 (- 2) + 2 (- 1) = - 8 (Substituting x = - 2 and y = - 1) \\ - 6 - 2 = - 8 \\ - 8 = - 8 \end{matrix}$

Step 3. Conclusion.

Since both sides of equation are equal, therefore, the ordered pair $(- 2, - 1)$ is a solution for the given equation.
