Question

What is the slope of y = -4?

Answer 1

The general expression for any straight line is:

`y=mx+b`

Where:

• m is the slope of the line

,

• b is the y-axis intercept

In this case, we have a straight line with equation

`y=-4\text{ }\rightarrow y=0x-4`

Meaning that the slope of such line is 0, and the y-axis intercept is -4.

in fact, it is a horizontal line that passes through y=-4

Any horizontal line has a slope of 0

Answer: The slope of y= -4 is 0
