Best ResponseYou've already chosen the best response.0Try to draw a diagram roughly, points A and C are on the x axis. So from C to B the line will go up (positive slope), and from B to A the line will go down (negative slope). Does that makes any sense? :)

Best ResponseYou've already chosen the best response.0slope of AB=(20)/(916)=2/7 AB=sqrt[(916)^2+(20)^2]=sqrt(49+4)=sqrt53 BC=sqrt[(09)^2+(02)^2]=sqrt85 AC=sqrt [(016)^2+(00)^2]=16 neither AC^2=BC^2+AB^2,Because 53+85=138 not =to 256 nor BC^2=AC^2+AB^2,Because 256+53=309 not= to 85 AB is not an altitude of triangle ABC though it has slope 2/7
