Write an equation of the line. helppp

y=-x-4

Step-by-step explanation:

Just ask.

Hope this helped! :)

y = -1x - 4

Step-by-step explanation:

Slope (m) = -1

Point on line: (-1,-3)

b from graph: -4

point intercept form: y=mx+b

Use values given and plug into this equation:

(-3)=(-1)(-1)+b

(-3)=(1)+b

b=-4

Using slope-intercept form we find the resulting equation:

y = -1x - 4

We can check if this is right because b is the y intercept. On the graph we see that the y intercept of the line is at -4, so this equation is correct.

I can fix any mistakes if needed. Consider marking brainliest thanks :)
