    Answer:

    Slope = -4

    Step-by-step explanation:

    Given points are :

    (-1,30) and (4, 10)

    We need to find the slope of the line that passes through these points.

    We know that, the formula for the slope of line is given by :

    m=\dfrac{y_2-y_1}{x_2-x_1}

    We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

    Put values in the above formula.

    m=\dfrac{10-30}{4-(-1)}\\\\=\dfrac{-20}{5}\\\\=-4

    So, the slope of the line is -4.
