5(-2) = -10, so 5(-2)(-11) = (-10)(-11) = 110
The length is 10.
Since the two points share the same y-coordinate, the segment rt is horizontal.
This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.
So, we have
The ratio is 9:81 which is equivalent to 1:9
The answer would be the first 1.
