-4x -y + 17 should be your answer in point slope form
---------------------------
First I tried to find the slope intercept form because it is easier for me
Plugging in the slope to the equation first.
y=-4x+b
----------------------------
To solve for B I plug in the points (4,1) for x and y in y=-4x+b
1-(-4)(4) = 17
17 is b, the equation is y=-4x+17
-------------------------------------------
I then convert this form to point slope, turning it into
-4x -y + 17
