Answer:
Step-by-step explanation:
1. 0.4y = x is a direct proportion. It'd be more appropriate to write this as
y = x / 0.4, or y = 2.5x, in which case 2.5 is the constant of proportionality.
2. x = 1 - 2y is not a direct proportion because of the offset (1). A line representing a direct proportion must go through the origin (0, 0); this particular line does not do that.

Answer:
Graph C represents a decreasing function.
Step-by-step explanation:
Graph A: Since y does not change when x increases from 0 to 6, this graph (a horizontal line) represents a constant function. REJECT this choice.
Graph B: The line connecting (0, 0) to (6, 6) is a straight line with slope +1; it's an increasing function. REJECT this choice.
Graph C: As we go from (0, 5) to (6, 0), y decreases by 5. Thus, this is the correct answer choice.
Graph D is a vertical straight line; its slope is undefined. REJECT this choice.
