    x intercept at (7/3, 0)

    y intercept at (0,-3)

    Step-by-step explanation:

    9x-7y=21

    we need to find x and y intercepts

    To find x intercept, plug in 0 for y

    9x - 7 (0) = 21

    9x = 21

    divide by 9 on both sides

    x = 21 / 9 = 7/3

    so x intercept at (7/3, 0)

    To find y intercept, plug in 0 for x

    9 (0) - 7 (y) = 21

    -7y = 21

    divide by - 7 on both sides

    y = - 3

    so y intercept at (0,-3)
