Best ResponseYou've already chosen the best response.0I guess just find the slope of A(2,0) and B(4,4)

Best ResponseYou've already chosen the best response.1\[\huge slope_{AB}=\frac{y_By_A}{x_Bx_A}\]

Best ResponseYou've already chosen the best response.1if you use the formular on top taking the difference in y coordinates and the differnce in the x cordintaes you get the slope

Best ResponseYou've already chosen the best response.0So YB is 4 right? so i 40=4. and then for x its, 4(2)= 6. So 4/6?

Best ResponseYou've already chosen the best response.0So now that i know the slope is 2/3, how can i tell if anything is parallel to line AB? And then how can i tell what is perpendicular to line AB

Best ResponseYou've already chosen the best response.1parrallel means same slope so if a line \[l\] is parrallel and its gradient (slope)is \[\huge m_l\] then \[\huge m_l=m_{AB}\] for perpendicular\[\huge m_{l}m_{AB}=1\]
