[tex]B = \frac{-2-(-17)}{5-8} = \frac{-2+17}{-3} = \frac{15}{-3} = -5\\[/tex]
[tex]\\C = \frac{-4-5}{-5-6} = \frac{-9}{-11} = \frac{9}{11} \\\\E = 2-\frac{-18}{-3} +6 = \frac{2}{1} - \frac{-18}{-3} + \frac{6}{1} = \frac{-6}{-3} - \frac{-18}{-3}+\frac{-18}{-3} = \frac{12}{-3} +\frac{-18}{-3} = \frac{-6}{-3} =2 \\\\G= \frac{[-2*(-4)]*[3*(-3)]}{(-4,5)*2} = \frac{[8]*[(-9)]}{-9} = \frac{-72}{-9} = \frac{72}{9}= 8\\ \\I= \frac{[-9*(-3)]-[(-3)*(-5)]}{[15/(-3)]-2} = \frac{[3]-[15]}{[-5]-2} = \frac{-12}{-7} = -\frac{12}{7}[/tex]
