A fan blade spins at a constant rate. This spinning is known as revolutions. The equation y=750x represents the number of revolutions (y) the fan blade makes in x minutes. List ordered pairs, (x, y), to represent the number of revolutions the fan makes for minutes 0,1,2, and 3.

    (1, 750)

    (2, 1500)

    (3, 2250)

    Step-by-step explanation:

    To list the ordered pairs (x, y) we need to calculated the number of revolutions for minutes 0, 1, 2 and 3.

    To calculated the number of revolutions for 0 minutes, we need to replace x by 0 in the initial equation and solve for y as:

    y = 750*x

    y = 750*0

    y = 0

    It means that our first ordered pair is (0,0), because when we replace x by 0 we get y equal to 0

    At the same way, if we replace x by 1, we get:

    y = 750*x

    y = 750 * (1)

    y = 750

    So, our second ordered pair is (1, 750)

    Then, replacing x by 2, we get:

    y = 750*x

    y = 750 * (2)

    y = 1500

    So, our third ordered pair is (2, 1500)

    Finally, replacing x by 3, we get:

    y = 750*x

    y = 750 * (3)

    y = 2250

    So, our last ordered pair is (3, 2250)
