Question

The graph of the equation y=-2 is a line

Answer 1

y=-2 is a straight line

Explanation:

We have the equation

`y = - 2`

This equation is of the form:

`y = c`

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.
