Answer:
-3
Explanation:
A line has a point where it crosses the y-axis.
The y-axis is the vertical axis in the plane, and the point where the line intercept the y-axis is called the y-intercept.
In this case we need to analyze the graph and see at what point the line and the y-axis meet.
This point is -3.
because at y = -3 the line is crossing the vertical axis.
The y-intercept is -3
