Equation of line is:
[tex]y+2 = 0[/tex]
Step-by-step explanation:
The slope is defined the rate of change of line w.r.t x. When a line is horizontal. it is parallel to x-axis which means that it's slope is equal to zero.
So the slope intercept form of equation
[tex]y = mx+b[/tex]
become
[tex]y = b[/tex]
Given point is: (-4,-2)
Putting the value of y in equation
[tex]b = -2[/tex]
So the equation will become:
[tex]y = -2[/tex]
It can also be written as:
[tex]y+2 = 0[/tex]
