Answer:
y=-2 is a straight line
Step-by-step explanation:
We have the equation
[tex]y = - 2[/tex]
This equation is of the form:
[tex]y = c[/tex]
where c is a constant.
Equations of such lines are horizontal lines that passes through (0,c).
Since we have c=-2 in this case, our horizontal line will pass through (0,-2).
We draw a line parallel to the x-axis that intercepts the y-axis at -2.
