Final answer:
The general linear equation of a vertical line that passes through the point (3,0) is x = 3.
Step-by-step explanation:
To find the general linear equation of a vertical line, we need to determine the x-value at which the line passes through the point. Since a vertical line has an undefined slope, we know that the equation will have the form x = c, where c is the x-coordinate of the point. In this case, the line passes through the point (3,0), so the equation is x = 3.
