ganeshie8 · Answer

use the slope formula ?

ganeshie8 · Answer

slope of line passong through points $(x_1, y_1)$ and $(x_2, y_2)$ is :  

$\large  \frac{y_2 - y_1}{x_2-x_1}$

ganeshie8 · Answer

K(c + d, c - d), L(c - d, c + d)
    x1        y1         x2      y2

*positive

ganeshie8 · Answer

K(c + d, c - d), L(c - d, c + d)
    x1        y1         x2      y2


$\large  \frac{y_2 - y_1}{x_2-x_1}$

$\large  \frac{(c+d) - (c-d)}{(c-d)-(c+d)}$

ganeshie8 · Answer

K(c + d, c - d), L(c - d, c + d)
    x1        y1         x2      y2


$\large  \frac{y_2 - y_1}{x_2-x_1}$

$\large  \frac{(c+d) - (c-d)}{(c-d)-(c+d)}$

$\large  \frac{c+d - c+d}{c-d-c-d}$

$\large  \frac{2d}{-2d}$

$\large   -1$
