A. y – 4 = 3( x – 1) (the answer was A)

B. 1 – y = 3(x – 4)

C. y₁ – 4 = 3(1 – x₁)

D. 1 – y₁ = 3(4 – x₁)

    The equation of a line in a point-slope form is

    y-y_1=m(x-x_1), where m is a slope of the line and (x_1,y_1) is the point that line is passing through.

    If slope m=3, then the equation will be

    y-y_1=3(x-x_1).

    The line is passing through the point (1,4), then the equation of the line is:

    y-4=3(x-1).
