Is line k parallel to line h why or why not A line k passes through the points 4 comma 2 and negative 4 comma 4 A second line h passes through the points negative 8 comma1 and 8 comma negative 3?

Answer 1

Line k: (4, 2), (-4, 4)
slope mk = (4 - 2)/(-4 - 4) = 2/-8 = - 1/4

Line h: (-8, 1), (8, -3)
slope mh = (-3 - 1)/(8 - -8) = -4/16 = - 1/4

Since both lines have equal slopes, - 1/4, the lines are parallel.
