plz help plz dont skip
Given m = 2 and the point (-1, 7), which of the following is the point-slope form of the equation?

y – 7 = 2(x – 1)

y + 7 = 2(x – 1)

y + 7 = 2(x + 1)

y – 7 = 2(x + 1)

    Option D: y-7=2(x+1) is the equation of line in point – slope form

    Explanation:

    Given that the slope is m=2 and the point (-1,7)

    We need to determine the equation of the line in point – slope form.

    The point – slope form can be determined using the formula,

    y-y_1=m(x-x_1)

    Let us substitute the point (-1,7) and the slope m=2 in the above formula.

    Thus, we have,

    y-7=2(x-(-1))

    Simplifying the terms, we get,

    y-7=2(x+1)

    Thus, the equation of the line in point – slope form is y-7=2(x+1)

    Therefore, Option D is the correct answer.
