Answer:
The x - intercept of the line is (-4, 0).
Step-by-step explanation:
The <em>x</em>-intercept is the point from which the graph passes through the <em>x</em>-axis.
At the <em>x-</em>intercept y = 0.
The provided line is:
Substitute y = 0 in this equation to determine the <em>x</em>-intercept as follows:

Thus, the <em>x</em>-intercept is (-4, 0).
