$(y - color(red)(4)) = color(blue)(-10)(x - color(red)(1))$

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:

$(y - color(red)(4)) = color(blue)(-10)(x - color(red)(1))$
