Question

Find the equation of the line that passes through the given point and has the given slope. (Use x as your variable.)(−2, −7), m = 0

Answer 1

General equation of line :

`y=mx+c`

where:

`\begin{gathered} m=\text{slope} \\ c=\text{ y-intercept} \\ (x,y)=(-2,-7) \end{gathered}`
`\begin{gathered} y=mx+c \\ y=0(x)+c \\ -7=0(-2)+c \\ c=-7 \end{gathered}`

so equation of line:

`\begin{gathered} y=mx+c \\ y=0(x)-7 \\ y=-7 \end{gathered}`
