A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions.  The equation of a line is y = mx + b (that’s for all my mathematicians!  And yes, I do realize that equation is the slope-intercept form.)

Lines can run parallel or perpendicular.  We can travel the world via cruise line or airline.  Why not sail across a river gorge on a zip line or sail a boat using a jib line?  We can cross a line or draw the line.  Sometimes lives are forever changed by pickup lines, party lines and picket lines. There are some who define the world with hard lines, fine lines or blurred lines, even straight and narrow lines.

We get in lines, wait in lines, color inside the lines, and tow the line…at least those of us with a certain upbringing anyway.  We can read headlines, bylines, tag lines and between the lines.  We begin at the starting line and end at the finish line.  And to flat line can mean the end of the line.

Lines have tremendous visual appeal to me.  These are some of my favorite photographs with prominent lines.
