Final answer:
The rate of change of y as a function of x is constant and the function is non-linear, the function value y is not 0 for all x, the y-intercept is 0, and when x = 6, y = 6.
Step-by-step explanation:
The question involves understanding the relationship between two variables, x and y, and how to interpret the features of a graph representing a function. To fill in the blanks: As x increases, y's rate of change for y as a function of x is constant, therefore, the function is linear. For all values of x, the function value y is not 0. The y-intercept of the graph is the function value y = 0. When x = 6, the function value y = 6. The correct answer is B) Constant, non-linear, is not, 0, 6.
