Equations {parametric equation} can depend on one variable. For example, line has parametric equations x = x1 + t*A and y = y1 + t*B, where t is parameter, A and B are constants, x and y are coordinates, and (x1,y1) is point on line. Line slope is B/A, if A is not 0. If A = 0, line is parallel to y-axis.
