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
