How do you graph x plus y equals -5?

Answer 1

Put x = 0. The equation is then y = 0 + 5 or y = 5

Mark the point (0,5).

Put y = 0. The equation then becomes 0 = x + 5 or x = -5

Mark the point (-5, 0)

Joint the two points and extend the line in both directions.

Answer 2

-- Mark a tiny pencil dot on the x-axis at x=-5 .

-- Mark another tiny pencil dot on the y-axis at y=-5.

-- Carefully place your ruler on the paper so that its edge touches both tiny dots.

-- With your pencil, draw a line segment along the edge of the ruler, through both

tiny dots, and as far as you like in each direction (without going off of the paper).

The line segment you drew is a portion of the graph of [ x + y = -5 ].

It's not possible to draw the complete graph. It's just more of the same line, but

the line "goes to infinity", and it can never stop in either direction.
