![x=3](https://img.qammunity.org/2022/formulas/mathematics/high-school/syjc43lciy5cni0r21ioxc8e8fe9kq09yb.png)
Explanation:
Normally, linear equations would be written in slope-intercept form,
, where
is the slope and
is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like
, where
is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be
.
