Answer:
y = -x - 4
Step-by-step explanation:
Looking at this graph straight off the bat we see the line is going downwards from left to right which is an indication of a negative slope. The slope is 1 considering the line's rise/run (2 units/2 units down on the graph). Thus, we know our slope is 2/2 = 1. Thus, our slope would appear as -(1)x or -x in the equation.
Next, we need to identify where the line crosses the y-axis to identify our y-axis point. Tracing the line, we see that it comes into contact with the vertical y-axis at -4 (4 units South on the y-axis).
Putting these both together we see the equation of the line is y = -x - 4.
