Final answer:
The slope of the line is 1/2 and the y-intercept is -1/2.
Step-by-step explanation:
The equation given is x - 2y - 1 = 0. To find the slope and y-intercept, we need to rewrite the equation in the form y = mx + b, where m is the slope and b is the y-intercept.
First, let's isolate y. Start by subtracting x from both sides to get -2y = -x + 1. Then, divide both sides by -2 to get y = (1/2)x - 1/2.
So, the slope is 1/2 and the y-intercept is -1/2.
