Question

Draw the graph representing the equation of x+y=0​

Answer 1

Explanation:

The given equation is x+y=0, i.e., y=−x.

Any point on the graph of y−x, will have x and y coordinated of opposite signs.

As the points (−1,1) and (−3,3) have x and y coordinated of opposite signs, so these points satisfy the given equation and the two points determine a unique line, hence the given statement is true.
