Question Analysis
This question involves identifying the type of relationship described by the equation  with reference to its graph. The main focus is on distinguishing between linear and nonlinear relationships based on the form of the equation and the characteristics of its graph.

Key Concept Explanation
A linear relationship between two variables x and y is one that can be represented by an equation of the form , where m (slope) and b (y-intercept) are constants. The highest power of x in such an equation is 1, and its graph is a straight line.
A nonlinear relationship cannot be expressed in the form . It involves variables with exponents other than 1 (e.g.,
