To find the y-intercept of the parabola given by the equation \( y = x^2 - 5x \), we need to evaluate the equation when \( x = 0 \).
Substituting \( x = 0 \) into the equation:
\[ y = (0)^2 - 5(0) = 0 - 0 = 0 \]
Thus, the y-intercept is \( y = 0 \).
So, the answer is:
\[ (0, 0) \] which indicates that the parabola intersects the y-axis at the origin.
