The equation y = 7x represents a linear relationship where the value of y is always 7 times the value of x. Therefore, all ordered pairs for this equation will have y as a multiple of 7x. For example, when x = 1, y = 7; when x = 2, y = 14; and so on. The ordered pairs for y = 7x will be in the form (x, 7x).
