Find the following:

The y coordinate of any point on the line through (1, 0), parallel to the y – axis

Since the line is parallel to y – axis , its equation will be of the form x = c, where c is a constant.

Point (1,0) is on the line, therefore, it will satisfy the equation of the line.

Putting x = 1 in the equation of a line,

We get,

1 = c.

Therefore, the equation of line will be x = 1.

Hence, y coordinate of any point on the line through (1,0), parallel to the y axis is 1.
