Short Answer

Expert verified

The graph of the given equation is

Step by step solution

Given information

The equation is given as $x + 2 y = 4$ to get the graph.

Find the intercepts

Apply the definition of the intercepts to find the intercepts of the given equation.

The intercepts of the given equation are the points where the corresponding variables become zero.
Hence substitute the associated variables zero into the given equation to find the required intercepts.

$\begin{array}{rcl} x + 2 y & = & 4 \\ x + 2 (0) & = & 4 \\ x & = & 4 \\ x + 2 y & = & 4 \\ 0 + 2 y & = & 4 \\ 2 y & = & 4 \\ y & = & \frac{4}{2} \\ y & = & 2 \end{array}$

Graph the equation using the intercepts

The graph of the linear equation is a straight line that passes through its intercepts.

As obtained, the intercepts of the given equation are (4,0) and (0,2).
Hence join the intercepts using a straight line to get the required graph of the equation.
