The answer is y=-x

Step-by-step 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

Answer:b

Explanation: If you look at the line on the graph, you can see that it is going downward, meaning it has a negative slope, and choice b is the only one that has a negative slope
