172. The slope of a straight line is the ratio of the:
173. There are two sets of (x,y) points on a straight line in a two-variable graph with y on the
vertical axis and x on the horizontal axis. If one set of points was (0,6) and the other set
(6,18), the linear equation for the line would be:
174. There are two sets of (x,y) points on a straight line in a two-variable graph with y on the
