Answer:
0
Step-by-step explanation:
y = -4 is a horizontal line
y = mx+b
y = 0x -4
We do not have an x terms so we have a slope of zero
Horizontal lines have a slope of zero
The equation y = -4 is a flat or horizontal line.
Horizontal lines have a slope of 0.
So y = -4 can be thought of as y = 0x - 4
This linear equation has a slope equal
to 0 and a y-intercept equal to -4.
