Final answer:
The y-intercept of the equation x - 2y = 8 is -4.
Step-by-step explanation:
The equation x - 2y = 8 represents a linear equation in standard form. To find the y-intercept, we can set x = 0 and solve for y.
Substituting x = 0 into the equation, we have 0 - 2y = 8.
Simplifying, we get -2y = 8 and dividing by -2, y = -4.
Therefore, the y-intercept is -4.
