Since the equation y = -4 represents a horizontal line, then the slope of the line is 0.
The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
That's a vertical line; the slope is not defined.

Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
the slope of the line is -4
Slope = 4
Since the equation y = -4 represents a horizontal line, then the slope of the line is 0.
Zero. Y=4 is a horizontal line.
The line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
The slope is -4
That's a vertical line; the slope is not defined.
