Answer: See Graph Below.
Step-by-step explanation:
When asked to graph the line with "y-intercept 8" and "slope -1/2" we can recognize that this graph is linear, with a negative slope.
In order to graph with such directions, one must know that the y-intercept is where the "starting point is" since it is 8, it would be (0,8).
Now the slope is read by the numerator depending on the positive or negative, can be treated as up 1 or down 1 respectively. In this scenario, we have a negative one, which means the graph is progressively moving downward.
As for the denominator of the slope, it follows through with the negative correlation of the numerator, so it would be going forward 2 after the initial downward of the 1.
Please see Figure (1) for a proper placement of the y-intercept, as well as how the slope progresses.
