The room is not in shape of a square but a rectangle.

Question says Length is: 19 inches

Diagonal is: 20.6 inches

In a square all sides are equal

Rectangle has just two sides equal

The slope would be C) -1/2

Step-by-step explanation:

To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)

m(slope) = (y2 - y1)/(x2 - x1)

m = (-3 - -4)/(0 - 2)

m = 1/-2

m = -1/2
