Chapter 8: Q6. (page 410)

Tell whether the ordered pair is a solution of $y = 5 x - 7$ .
$(- 3, - 22)$

Short Answer

Expert verified

The ordered pair $(- 3, - 22)$ is a solution for the given equation.

Step by step solution

Step 1. Given Information

The given equation is $y = 5 x - 7$ .

Step 2. Calculation.

To check whether the ordered pair $(- 3, - 22)$ is a solution forthe given equationor not, we will substitute coordinates of point $(- 3, - 22)$ in our given equation as shown below:

$\begin{array}{l} y = 5 x - 7 (Givenequation) \\ - 22 = 5 (- 3) - 7 (Substituting x = - 3 and y = - 22) \\ - 22 = - 15 - 7 \\ - 22 = - 22 \end{array}$

Since both sides of equation are equal.

Step 3. Conclusion.

The ordered pair $(- 3, - 22)$ is a solution for the given equation.
