Answer:
x = 8
Step-by-step explanation:
The general equation of a vertical line that passes through "a" is
[tex] x = a[/tex].
Notice that x remains fixed at value "a" and y can take any value.
This can be understood by rewritting the above equation as
[tex] x + 0*y = a[/tex].
Then, the points ... (a, -2), (a, -1), (a, 0), (a, 1),(a, 2)... vertically aligned satisfy the above equations.
Now, returning to our specific exercise, we need the vertical line that passes through (8, -2). Since, the line is vertical, we have to focus on x-coordinate of the given point, and its value is 8.
Then, the equation of the vertical line passing through the point (8, −2) is
[tex] x = 8[/tex].
