Tell whether the ordered pair is a solution of the equation.

x-2y=8;-6,-7

Short Answer

Expert verified

The ordered pair -6,-7is a solution for the given equation.

Step by step solution

01

Step 1. Given information.

The given equation is x-2y=8.

02

Step 2. Calculation.

To check whether the ordered pair -6,-7 is a solution for the given equation or not, we will substitute coordinates of point -6,-7 in our given equation as shown below:

x鈭�2y=8Givenequation鈭�6鈭�2(鈭�7)=8Substitutingx=鈭�6andy=鈭�7鈭�6+14=88=8

Since both sides of equation are equal, therefore, the ordered pair -6,-7 is a solution for the given equation.

03

Step 3. Conclusion.

The given point is the solution of the given equation.
