Answer:

y + 3x = 0

Explanation:

The formula for equation of the line is :

y - y1 = m ( x - x1 )

NB: The m is the slope, then use substitution, solve and equate everything to 0

Answer:

Explanation:

The equation of line passing from point (x1,y1) and having slope m is

y- y1 =m(x- x1)

m=-3, x1=1, y1=-3

y-(-3) = -3(x-1)

y+3=-3(x-1)

y+3=-3x+3

y=-3x

3x+y=0
