Rita is developing an equation that will represent the same proportional relationship as the graph.

On a coordinate plane, a line goes through points (0, 0) and (4, 7).
How will the ordered pair help her when she finds the equation?
The product of the coordinates will be a constant term in the equation.
The quotient of the coordinates will be a constant term in the equation.
The product of the coordinates will be a coefficient in the equation.
The quotient of the coordinates will be a coefficient in the equation.
