Question

Find the slope of the line that contains the points named.

K(c + d, c - d), L(c - d, c + d)
a. -1
b. 1
c. 0

Answer 1

Hello,

Answer A

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

Answer 2

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

Explanation:

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

`Slope\:of\:line=(y_2-y_1)/(x_2-x_1)`

`Slope\:of\:line\:KL=(c+d-(c-d))/(c-d-(c+d))`

`=(c+d-c+d)/(c-d-c-d)`

`=(2d)/(-2d)`

`=-1`

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