To calculate the y-coordinate of the midpoint between the points (1, -2) and (7, 6), you can use the midpoint formula. The midpoint \((x_m, y_m)\) is given by the following formulas:

\[ x_m = \frac{x_1 + x_2}{2} \] \[ y_m = \frac{y_1 + y_2}{2} \]

For the points (1, -2) and (7, 6):

  • \(y_1 = -2\)
  • \(y_2 = 6\)

Now, plug in the values into the formula for the y-coordinate:

\[ y_m = \frac{-2 + 6}{2} = \frac{4}{2} = 2 \]

So, the y-coordinate of the midpoint is 2.

Based on the options provided, the correct response is 1 + 72.
