Answer:
This is a graph of y = -x,
slope of graph = -1,
Y-intercept = 0
This line passes through the origin, so its equation follows the form
[tex]y=mx[/tex]
The slope [tex]m[/tex] can be computed using the "rise over run" technique: each time you increase x by 1, y decreases by 2. So, the slope is -2.
The equation is thus
[tex]y=-2x[/tex]
