I put what I thought but came out wrong, please help

Answer:
Sir, as for as I can tell that is the correct answer. Maybe you put it in wrong or added a space but that’s correct 100%.
Unless it’s not supposed to be in y = mx + b format?
Step-by-step explanation:
Answer:
y = -x - 1
Step-by-step explanation:
The equation of the line is written in the slope-intercept form,
y = mx + b
where m represents the slope
number that describes both the direction and the steepness of the line
slope = rise/run
b represents the y-intercept
point where crosses the y-axis
y = mx + b → y = -1x + (-1)
this can be simplified by -x - 1
