Answer:
A screenshot of the graph is attached.
Step-by-step explanation:
The y-intercept of a graph, where it crosses the y-axis, will be the point where x=0. In this case, if x=0, y=0; this makes the origin (0, 0) the y-intercept.
The slope of this line is -1. This means that for every increase of 1 in the x-axis, the y-coordinate will decrease by 1.
This tells us that from (0, 0), the graph will go to (1, -1); then to (2, -2), (3, -3), etc.
