Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)
