Answer

a.)undefined b.) 0 c.)$\frac{-5}{12}$ d.)$\frac{-4}{3}$

Work Step by Step

a.) (6,4) and (6,-3) Slope formula m =$\frac{y2-y1}{x2-x1}$ = $\frac{-3-4}{6-6}$ = $\frac{-7}{0}$ = undefined b.)(1,4)and (-5,4) Slope formula m =$\frac{y2-y1}{x2-x1}$ = $\frac{4-4}{-5-1}$ = $\frac{0}{-6}$ = 0 c.)(-5,2) and (7,-3) Slope formula m =$\frac{y2-y1}{x2-x1}$ = $\frac{-3-2}{7+5}$ = $\frac{-5}{12}$ d.)(x-3,y+2) and(x,y-2) Slope formula m =$\frac{y2-y1}{x2-x1}$ = $\frac{y-2-y-2}{x-x+3}$ = $\frac{-4}{3}$
