Question

What is the slope of y = -4?

Answer 1

Answer: zero slope

Explanation: The equation y = -4 can be thought of as y = 0x - 4.

So our line has a slope of 0 and a y-intercept of -4.

This line is a flat line or horizontal.

In fact, when the equation of any line reads y = a number, its slope

will always be 0 because it's a horizontal line.

So, this line has a slope equal to zero.
