    Answer:

    In your equation 4x+5y=-9, you’ve got to but your equation in slope intercept form which is y=mx+b.

    First we need to get the y by itself.

    Subtract 4x from each side to get:

    5y=-4x-9

    Next we want to divide both sides by 5.

    y=-4/5x-9/5

    Your slope is m which in our case -4/5.

    Then our y-intercept is b or -9/5.

    Your answer would then be C. slope=-4/5 and y-intercept=-9/5.

    Hope this helps 😉
