Identify the y-intercept definition

Using the y-intercept and Coordinate Plane knowledge points
The \(y\)-intercept is the point where the graph crosses the \(y\)-axis, which always occurs where the \(x\)-coordinate is \(0\).

Locate the point on the graph

Using the Ordered Pairs knowledge point
Looking at the vertical \(y\)-axis, the parabola intersects it at the value \(4\).
This corresponds to the ordered pair \((0, 4)\).
