Question

A coordinate plane with a vertical line passing through (negative 3, negative 3), (negative 3, 0) and (negative 3, 3).
What is the equation of the graphed line written in standard form?

x = –3
y = –3
x + y = –3
x – y = –3

Answer 1

x = −3

Explanation: The line is vertical through x = −3 (it has the same x-coordinate for all points), so its equation is x = −3 (or in standard form x + 0y = −3).
