Three vertices of parallelogram abcd are a(−1,5), b(2,1) and d(−2,−3). identify the coordinates of vertex c. !

(1,-7) or option c

Step-by-step explanation:

This is a late response but maybe it can help others.

Basically, put the coordinates in the question into demos then add all the multiple chose options.

Then you are going to want to find the slope or basically count how many over and up or down one point is the others in the questions, and you want to find the multiple-choice option that is the same distance away and makes the dots into a rhombus looking shape. Sorry, this is a very bad explanation lol

55/i dont know i do it for the points

step-by-step explanation:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
