Choose the point slope form of the equation below that represents the line that passes though the points (-1, 6) and has a slope of -3. y-6=-3x-3 y=-3x+3 3x+y=3 y-6=-3(x+1)

Point slope form is 
y - y1 = m ( x- x1)  
y1 is the y coordinate of the first point
m is the slope
x1 is the x coordinate of the first point

We are given point (-1, 6) 
and the slope of -3

Plug into the point slope form
y - 6 = -3 ( x - -  1)
y - 6 = -3 (x + 1)

Hope this helps :)
