Answer:

y = -x

Step-by-step explanation:

The line has a slope of -1 and it passes through point (0,0)

Taking another point (x,y) on the line;

Slope = change in y ÷ change in x

For our case; slope = $\frac{y - 0}{x - 0} = -1$

Cross multiplying this gives;

y = -x

3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
