Answer:

The needed line equation is : x + y + 2 = 0

Explanation:

The slope m of the given line equation = -1

The points through which the line passes is (1,-3).

Now,as we know:

The POINT SLOPE form of the equation with point (x0,y0) is given as:

y - y0 = m (x-x0)

So, the equation if line q=with m = -1 and (x0,y0) = (1,-3) is given as

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

or, y + 3 = 1 -x

or, x + y + 2 = 0

Hence, the needed line equation is : x + y + 2 = 0
