    Find the slope of (a) |dw:1365962439060:dw| 1. A(-2, 0) and B(4,4)

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

    \[\huge slope_{AB}=\frac{y_B-y_A}{x_B-x_A}\]

    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 4-0=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\[\huge m_{l}m_{AB}=-1\]
