The graph that models this relationship is a linear equation of the form y = 3x.
The graph that models this relationship is a straight line. The slope of the line represents the ratio of sheep to horses, which in this case is 3:1. Therefore, for every 1 increase in the number of horses, there will be a corresponding 3 increase in the number of sheep. The equation representing this relationship is y = 3x, where y is the number of sheep and x is the number of horses.
