    Answer:

    (y – 7) = 4(x + 4) or y = 4x + 23

    Step-by-step explanation:

    In point- slope form, the equation of a line is (y – y₁) = m(x – x₁)

    The slope is given as 4, and so is point (x₁ , y₁). Substitute (-4, 7) as (x₁ , y₁), and do not forget to change the sign to a positive when you get a double negative.

    (y – 7) = 4(x + 4) can further be expanded to slope- intercept form as y = 4x + 23
