Question 754232: A line passes through the points (4,2) and (-4,4). A second line h passes through the points (-8,1) and (8,3). Is line k parallel to line h? Why or Why not?
Pleases help me figure out how to solve this step by step!!!

You can put this solution on YOUR website! A line passes through the points (4,2) and (-4,4). A second line h passes through the points (-8,1) and (8,3). Is line k parallel to line h? Why or Why not?
-------------
Find the slope of each line.
A line passes through the points (4,2) and (-4,4).
slope = diffy/diffx
= (4-2)/(-4-4)
= -1/4
===============
Find the slope of the 2nd line.
Iff the slope is the same, they're parallel.
