Graph each equation.
$x + 2 y = - 1$

Short Answer

Expert verified

The graph of the equation $x + 2 y = - 1$ is:

Step by step solution

Step 1. Find the x and y-intercepts of the equation x+2y=−1.

To find the x-intercept, substitute 0 for y and find the value of x.

$x + 2 y = - 1 x + 2 (0) = - 1 x + 0 = - 1 x = - 1$

Therefore, the x-intercept is $- 1$ .

As, the x-intercept is $- 1$ that means the graph of $x + 2 y = - 1$ will intersect the x-axis at $(- 1, 0)$ .

To find the y-intercept, substitute 0 for x and find the value of y.

$x + 2 y = - 1 0 + 2 y = - 1 2 y = - 1 y = - \frac{1}{2}$

Therefore, the y-intercept is $\frac{- 1}{2}$ .

As, the y-intercept is $\frac{- 1}{2}$ that means the graph of $x + 2 y = - 1$ will intersect the y-axis at width="59">0,−12.

Step 2. Draw the graph of the equation x+2y=−1.

Draw the graph of the equation $x + 2 y = - 1$ by using the information that the graph of the equation $x + 2 y = - 1$ is a line passing through the points $(- 1, 0)$ and $(0, \frac{- 1}{2})$ .

Therefore, the graph of the equation $x + 2 y = - 1$ is:
