    Answer:

    The equation of the sraight line  3x- y+ 6 =0

    Step-by-step explanation:

    Explanation:-

    Given that the gradient of the function

       |gradf| = 3  and point (-1,3)

    Given that the slope of the line

     m = 3

    The equation of the straight line passing through the point(-1,3) and slope m =3

    [tex]y -y_{1} = m(x-x_{1} )[/tex]

    y-3 = 3(x-(-1))

    y-3 = 3x+3

    3x +3-y+3=0

    3x- y+ 6 =0

    Final answer:-

    The equation of the sraight line  3x- y+ 6 =0
