Answer:

B - y - 3 = -4(x + 2)

Step-by-step explanation:

Point slope form of a line

y - y_1 = m( x - x_ 1)

m = slope

Slope m has been given

Slope = -4

Substitute m into point slope form equation

y - y_1 = m( x - x_1)

y - y_1 = -4( x - x_1)

Substitute the point

( -2 , 3)

x_1 = -2

y _1 = 3

y - y_1 = m( x - x_1)

y - y_1 = -4( x - x_1)

y - 3 = -4( x - (-2))

y - 3 = -4(x + 2)

We do not open the bracket in point slope form except in slope intercept form which is

y = mx + c
