Determine whether each ordered pair is a solution of the given
equation.
3. (6, 4); y = 2x - 8
4. (8, 72); y = x÷9
5. (-3,-18); y = -6x
6. (5,64); y = 12x+4

3. (6, 4); y = 2x - 8       - solution to the eqaution

4. (8, 72); y = x÷9        - not a solution to the eqaution

5. (-3,-18); y = -6x        - not a solution to the eqaution

6. (5,64); y = 12x+4    - solution to the eqaution

Step-by-step explanation:

To check whether the given ordered pair satisfies the equation, we can directly put the respective values of “x” and “y” from the ordered pair in the equation and determine its validity.

3. (6, 4) and y = 2x – 8

Putting the values of x and y we get

4=(2*6)-8=12-8 which satisfies the equation

Hence this ordered pair is the solution for the equation.

4. (8, 72) and y = x÷9

Putting the values of x and y we get

72≠8/9 which does not satisfies the equation

Hence this ordered pair is not the solution for the equation

5. (-3,-18) and y = -6x

Putting the values of x and y we get

-18≠(-6*-3)=which does not satisfy the equation

Hence this ordered pair is not the solution for the equation

6. (5,64) and y = 12x+4

Putting the values of x and y we get

64=(12*5)+4=60+4 which satisfies the equation

Hence this ordered pair is the solution for the equation

answer: it is d
