Question

Find the slope of the line that contains the points named.
K(c + d, c - d), L(c - d, c + d) m = ? the formula for slope is y2-y1 over x2-x1= the slope

Answer 1

m = -1

K(c + d, c - d), L(c - d, c + d)

Using the slope formula,
m = [(c+d)-(c-d)] / [(c-d)-(c+d)]
= (c + d - c + d) / (c - d - c - d)
= 2d / -2d
= -1

Answer 2

Thanks again... i see where i made my mistake. :-)
