Draw the graph of $x + y = 7.$
Draw the graph of $x + y = 7.$
To draw the graph, we need at least two solutions of the equation. You can check that $x = 0$, $y = 7$, and $x = 7$, $y = 0$ are solutions of the given equation. So, you can use the following table to draw the graph :
| $x$ | $0$ | $7$ |
| $y$ | $7$ | $0$ |
Draw the graph by plotting the two points from Table $2$ and then by joining the same by a line (see Fig.)
