The answer is y=-x
Explanation:
In the formula y=mx+b, m stands for the slope while b stands for the y-intercept.
The slope, in this case, is negative one. You can see this by finding two points on the line and using the slope formula
y(2)-y(1)
————
x(2)-x(1)
As for the y-intercept. That is just the point at which the line crosses the y-axis. In this case, the line intercepts at y=0. So, you do not need to put anything in for ‘b’
So, when m=-1 and b=0, your equation is y=-x
