Finding Y-Intercept: Substituting x=0 into Equations

To determine if the given statement is true, consider the equation of the parabola $y = (x - p)^2$. The y-intercept occurs where the parabola crosses the y-axis, which is at $x = 0$.

Step 1: Substitute $x = 0$ into the equation:

$y = (0 - p)^2 = p^2$

Step 2: Calculate the y-intercept:

The y-intercept of the parabola is $y = p^2$.

Conclusion: The statement "To find the y-axis intercept, you substitute $x = 0$ into the equation and solve for $y$" is indeed True, as applying this method correctly determined the y-intercept for the given form of a parabola. Therefore, the answer to the problem is True.
