The point $\"\"$ .

Slope is undefined.

Draw a coordinate plane.

Plot the point $\"\"$ .

$\"\"$

Using slope find the next points.

Since the slope is undefined, the line is vertical.

A vertical line never moves left or right, the $\"\"$ coordinates of this line are always equals to $\"\"$ .

Write the other points with same $\"\"$ coordinates and $\"\"$ coordinates are different $\"\"$ , $\"\"$ .

Plot the points $\"\"$ and $\"\"$ .

Draw a line through these points.
