Final answer:
The y-intercept of the line is 4.
Step-by-step explanation:
To find the y-intercept of a line, we need to set x = 0 and solve for y. In the given equation, y - 2x = 4, let's substitute x = 0:
y - 2(0) = 4
y = 4
So the y-intercept of the line is 4. This means that the line intersects the y-axis at the point (0, 4).
