Final answer:
The point (12,8) is a solution to the equation 3/4x - 1 = y because when we substitute x = 12 into the equation, the resulting y-value is 8, which matches the y-value of the point.
Step-by-step explanation:
To determine if the point (12,8) is a solution to the equation 3/4x - 1 = y, we substitute the x-value of the point into the equation and check if the resulting y-value is equal to the y-value of the point.
Let's substitute x = 12 into the equation:
3/4 × 12 - 1 = y
→ 9 - 1 = y
→ 8 = y
Since the resulting y-value is 8, which matches the y-value of the point (12,8), we can conclude that the point is indeed a solution to the equation.
Therefore, the answer is: yes, the point (12,8) is a solution to the equation 3/4x - 1 = y.
