Question

What is the slope of y = -4?

Answer 1

We will investigate how to determine the slope ( m ) from an equation of a straight line.

The general slop-intercept form of an equation of a line is as follows:

`y\text{ = m}\cdot x\text{ + c}`

Where,

`\begin{gathered} m\colon\text{ Slope} \\ c\colon\text{ y-intercept} \end{gathered}`

We are given the following equation of a straight line:

`y\text{ = -4}`

We will employ the coefficient comparison method to evaluate the values of each parameter ( m and c ). Therefore,

`y\text{ = -4 }\equiv\text{ m}\cdot x\text{ + c}`

Hence,

`\begin{gathered} m\text{ = 0} \\ c\text{ = - 4} \end{gathered}`

The slope ( m ) of the given equation of line is as follows:

`0`
