Question

The Point of Intersection of two lines is given by $(a,b)$, then which of the following is/are true?

• A. $x=a$
• B. $y=a$
• C. $x=b$
• D. $y=b$

Answer 1

Answer: (A), (D)

$y=b$

When we write the coordinates, $x$- coordinate always comes first and then $y$ - coordinate in a point.

The point of intersection is $(a,b)$ which is formed when the lines $x=a$ and $y=b$ intersect.

Hence $x=a$ and $y=b$ are the two lines.

For example,
(2, 3) is a coordinate when the line $x=2$ and $y=3$ meets in the first quadrant.

$\therefore$ Option (a) and (d) are correct.
