    (0, 4) and ( - 7, 0)

    Step-by-step explanation:

    Given

    4x - 7y = - 28

    To find the y - intercept, let x = 0 in the equation and solve for y

    4 (0) - 7y = - 28

    - 7y = - 28 (divide both sides by - 7)

    y = 4 ← y - intercept ⇒ (0, 4)

    To find the x - intercept let y = 0 in the equation and solve for x

    4x - 7 (0) = - 28

    4x = - 28 (divide both sides by 4)

    x = - 7 ← x - intercept ⇒ ( - 7, 0)

    4x-7y+28=0

    7y = 4x + 28

    y = 4/7x + 4

    Y intercept = 4

    4x = 7y-28

    x = 7/4y - 7

    X intercept = - 7
