Final answer:
The slope of the line is 1/2 and the y-intercept is -1/2.
Step-by-step explanation:
In the given equation x - 2y - 1 = 0, we can rewrite it in the form y = mx + b, where m represents the slope and b represents the y-intercept. To find the slope, we need to isolate y in terms of x. Rearranging the equation, we get:
2y = x - 1
y = (1/2)x - 1/2
So, the slope of the line is 1/2 and the y-intercept is -1/2.
