Chapter 8: Q13. (page 410)

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

y=-4x+9;3,-3

Short Answer

Expert verified

The ordered pair 3,-3 is a solution for the given equation.

Step by step solution

01

Step 1. Given information.

The given equation is y=-4x+9

02

Step 2. Calculation.

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

y=鈭�4x+9Givenequation鈭�3=鈭�4(3)+9Substitutingx=3andy=鈭�3鈭�3=鈭�12+9鈭�3=鈭�3

Since both sides of equation are equal, therefore, the ordered pair 3,-3 is a solution for the given equation.

03

Step 3. Conclusion.

The given point is the solution of the given equation.
