Question

What is the slope of the line joining (8, 8) and (12, 6)? answer choices attached

Answer 1

$\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 8}}\quad ,&{{ 8}})\quad % (c,d) &({{ 12}}\quad ,&{{ 6}}) \end{array} \\\quad \\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{6-8}{12-8}$

Answer 2

Slope = y2-y1/x2-x1
m= 6-8/12-8
slope (m) = -1/2
