#(y - color(red)(1)) = color(blue)(-4)(x + color(red)(6))#

The point-slope formula states: #(y - color(red)(y_1)) = color(blue)(m)(x - color(red)(x_1))#

Where #color(blue)(m)# is the slope and #color(red)(((x_1, y_1)))# is a point the line passes through.

Substituting the values from the problem gives:

#(y - color(red)(1)) = color(blue)(-4)(x - color(red)(-6))#

#(y - color(red)(1)) = color(blue)(-4)(x + color(red)(6))#
