Find the value of k so that the line containing the points (−5,k) and (7,3) is parallel to the line containing the points (−8,−8) and (−1,−14)

Answer 1

slope = (-14+8)/(-1+8) = (3-k)/(7+5)

Answer 2

Find the value of k so that the line containing the points (-6,k)and (-3,4) is perpendicular to the line y=-5//6x-5.
