Question

The slope of diagonal AB is ___ , and it’s equation is ___.

Answer 1

Answer:

The slope of diagonal AB is 0 and its equation is $y=-2$.

Step-by-step explanation:

Horizontal lines have zero slope. Since diagonal AB represents a horizontal line (same y-value regardless of x-value), the slope of diagonal AB is 0.

Horizontal lines can be expressed as $y=n$ where $n$ is some real number. In this case, diagonal AB sits on a line with only y-values of -2, and therefore the equation of the line the diagonal is on is $\boxed{y=-2}$.
