Explanation:

Step1: Identify y-intercept definition

The y-intercept is the point where the graph crosses the y-axis (where $x=0$).

Step2: Locate intersection on graph

From the graph, the parabola crosses the y-axis at the point $(0, -8)$.

Answer:

The y-intercept is $\boldsymbol{-8}$ (or the point $\boldsymbol{(0, -8)}$)
