Question

On a coordinate plane, the location of 3 points are: (0,6),(5,-4), and (-1,-5). Where would the fourth point need to be located in order to form a parallelogram?

Answer 1

Answer:

(-6, 5)

Step-by-step explanation:

The slope of the segment from (0, 6) to (5, -4) is

m = (6--4)/(0-5) = (6+4)/(-5) = 10/(-5) = -2

The slope of the segment from (-1, -5) to (5, -4) is

m = (-5--4)/(-1-5) = (-5+4)/(-6) = (-1)/(-6) = 1/6

In order to be a parallelogram, the slopes of opposite sides must be the same.  This means the slope of the segment across from the segment with a slope of 1/6 must also have a slope of 1/6.

Working from (0, 6), to find the point with a slope of 1/6 we will work backward; going down 1 and back 6, we have (0-6, 6-1) = (-6, 5).

Answer 2

The fourth point would need to be located at,

( 5 , 7 )
