Question

vertical line

1. ( x = -3 )

Explanation:

Step1: Identify line type

The equation $x=-3$ is a vertical line, meaning every point on the line has an $x$-coordinate of $-3$, regardless of the $y$-value.

Step2: Locate position on grid

On the coordinate grid, find the vertical line that passes through $x=-3$ (3 units to the left of the origin $(0,0)$). Draw a straight vertical line through this $x$-value, extending across the entire grid.

Answer:

A vertical straight line passing through the point $(-3, y)$ for all real values of $y$, drawn 3 units left of the grid's origin.
