Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line goes through points (0, 0), (10, 40) and (negative 10, negative 40).

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
