To find the \( y \)-coordinates of the first two points on the graph of the equation given by the additive rule \( y = x + 25 \), we can substitute the \( x \)-values of 1 and 2 into the equation:
- For \( x = 1 \):
\[ y = 1 + 25 = 26 \]
Thus, the first point is \( (1, 26) \).
- For \( x = 2 \):
\[ y = 2 + 25 = 27 \]
Thus, the second point is \( (2, 27) \).
So, the \( y \)-coordinates of the first two points are:
- For \( (1, _) \): \( 26 \)
- For \( (2, _) \): \( 27 \)
In conclusion, the points are \( (1, 26) \) and \( (2, 27) \).
