Hi,

*Note: Inorder to be parallel lines, slopes must be equal

Checking out the slopes of the lines passing thru points given for each



(4,2) and (-4,4)

m = 4-2/-4-4 = 2/-8 = -1/4



(-8,1) and (8, -3)

m = -3-1/8-(-8)=-4/16 = -1/4

Slopes are equal, lines are parallel

 (4,2) and (-4,4. A second line h poasses through the points (-8,1) and (8, -3), is line k parallel to line h?

..

slope of line k = (4-2)/(-4-4)

=2/-8

=-1/4

..

slope of line h =(-3-1)/(8+8)

=-4/16

=-1/4

..

slopes are same so they are parallel
