Answer:
Explanation:
Given: PQRS is a parallelogram and the coordinates of P and S are (-1,6) and (-7,-3) respectively.
To find: The slope of QR.
Solution: The coordinates of P and S are (-1,6) and (-7,-3) respectively.
Then, Slope Of PS=

=

=

=

Thus, Slope of PS=
.
Now, since it is given that PQRS is a parallelogram, thus Slope of PS will be equal to the slope of QR, thus slope of QR=
.
