Hello,

Answer A

slope= (c+d-(c-d))/(c-d-(c+d))=2d/(-2d)=-1

Answer:

Option A is correct .i.e., Slope is -1.

Step-by-step explanation:

Given points are K(c+d , c-d) & L(c-d , c+d)

\(Slope\:of\:line=\frac{y_2-y_1}{x_2-x_1}\)

\(Slope\:of\:line\:KL=\frac{c+d-(c-d)}{c-d-(c+d)}\)

                                    \(=\frac{c+d-c+d}{c-d-c-d}\)

                                    \(=\frac{2d}{-2d}\)

                                    \(=-1\)

Therefore, Option A is correct .i.e., Slope is -1.
