Answer: See attached, or read below.
Explanation:
First, we see there is no b value, so there is no y-intercept. The line will intercept the graph at (0, 0), also known as the origin.
Next, we see a negative slope of -1/2. This means, starting at the origin, we will move down one unit and right two. Then repeat. Lastly, draw a straight line through all three points for our graph.
