Question 55909
Can someone please help me with this problem?

  I need to use the concept of slope to determine if the given figure is a parallelorgram or a rectangle.
I showed up above the page number and book, in case you have it.
I appreciate it.

Hi Sher,
I don't have your book, but I can tell you what to do.  
If the opposite sides have the same slopes they a parallel.  Both rectangles and parallelograms have opposite sides of identical slopes.

If the line segments that make up the corners have slopes that have opposite signs and are upside down, then  the corners are right angles and the figure is a rectangle.  

Happy Calculating!!!
