    So do it the old-fashioned way. Make a table of values and plot them. Or of course there is always Excel or something like that.

    Is this equation y = (1/4) ยท x ["one quarter times x"] or y = 1/(4x) ["one divided by four times x"]? What makes an equation linear? (The definition will tell you the answer without having to make a graph.) Do you recall the equation for a straight line on a graph?
