I guess just find the slope of A(2,0) and B(4,4)

The answer is 2/3. How do they get this?

if you use the formular on top taking the difference in y coordinates and the differnce in the x cordintaes you get the slope

So YB is 4 right? so i 40=4. and then for x its, 4(2)= 6. So 4/6?

So 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

parrallel 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\[\huge m_{l}m_{AB}=1\]
