Answer: 4
Step-by-step explanation: The y-intercept is a point
where a line crosses the y-axis.
All y-intercepts have an x-coordinate of zero.
The equation shown here is in slope-intercept form or y = mx + b form.
In this form, the m represents the slope and the b is y-intercept.
So here, we can tell that the y-intercept is 4.
