# Draw the graphof leniar equation x+y=4?

##### 2 Answers

graph{x+y=4 [-22.8, 22.81, -11.4, 11.42]}

#### Explanation:

now to find the points where it intersects put

x=0 in the equation to get y=4 ......hence we got our first point(0,4)

again put y=0 to get x=4...............hence we got our second point(4,0)

join both the lines and extend bothways to get the graph

See below

#### Explanation:

You can rewrite the equation as

To draw a line, you only need to sample two points, and to sample two points you choose two values for

So, this line passes through the points

Draw these two points and connect them, and you have the line.
