Answer: y = -x - 4
Explanation:
If you have a line with a y-intercept of -4 and a slope of -1, you can write the equation of the line in slope-intercept form, which is:
y = mx + b
y is the y-coordinate of a point on the line.
x is the x-coordinate of that point.
m is the slope of the line.
b is the y-intercept.
In this case, you have a slope (m) of -1 and a y-intercept (b) of -4. So, you can write the equation of the line as:
y = -x - 4
