SOLUTION: A line k passes through the points (4, 2) and (-4, and 4). A second line h passes through the points ( -8,1) and ( 8, -3). Is the line k parallel to line h? Why or why not?

Question 772604: A line k passes through the points (4, 2) and (-4, and 4). A second line h passes through the points ( -8,1) and ( 8, -3). Is the line k parallel to line h? Why or why not?

(I)
If slopes for k and h are equal, then k and h are parallel; but if all four given points are on the same line, then k and h are equal or, "congruent".

(II)

(III)
Are these lines the same?

The formula for b allows to quickly determine the y-intercept for a line from slope-intercept form. Pick any of the line's points.
k:
h:
