Given:
Slope of line = 0
Passing point (-2,-1)
The objective is to find the equation of line.
The slope intercept form of a line is given by:
[tex]y=mx+c[/tex]Where m is the slope of line and c is the y-intercept of line.
The y intercept of line is given as:
[tex]\begin{gathered} y=mx+c \\ -1=(0)(-2)+c \\ c=-1 \end{gathered}[/tex]The equation of line is:
[tex]\begin{gathered} y=mx+c \\ y=0(x)-1 \\ y=-1 \end{gathered}[/tex]Hence, the equation of line is y= - 1.
