Final answer:
After substituting the x and y values from the ordered pair (3.5, 6.8) into the equation Y = -1.2x - 2.6, it is clear that the equation does not hold, hence (3.5, 6.8) is not a solution to the equation.
Step-by-step explanation:
To determine if the ordered pair (3.5, 6.8) is a solution to the equation Y = -1.2x - 2.6, we need to substitute the x and y values from the ordered pair into the equation and check if the equation holds.
Substitute x with 3.5 and y with 6.8:
6.8 = -1.2(3.5) - 2.6
6.8 = -4.2 - 2.6
6.8 = -6.8
This is not true since 6.8 does not equal -6.8. Hence, the solution does not hold true, indicating that (3.5, 6.8) does not fulfill the equation. This discrepancy highlights the ordered pair's lack of conformity to the equation, showcasing the importance of meticulous validation while assessing solutions in mathematical contexts.
