This graph is labeled Streakline, open parentheses, lowercase x subscript one equals three, lowercase y subscript one equals one, capital K equals one, capital U equals four. This graph is a two-dimensional graph that displays positive and negative x coordinates and only positive y coordinates. The x coordinates go from negative four to positive four, in increments of one, and the y coordinates go from zero to one point two in increments of point two. The representation of the streakline is a red curve that starts out at approximately negative four, zero point four, and resembles a line with a slight curve upward until the point two, zero point six, when the graph starts curving upward exponentially.
