Question

A vertical line $l$ passes through the point $(2,3)$. A horizontal line $m$ passes through the point $(-1,6)$. Where do lines $l$ and $m$ intersect?

• A. $(0,5)$
• B. $(2,6)$
• C. $(6,2)$
• D. $(-1,3)$
• E. $(3,-1)$

Answer 1

The correct option is B $(2,6)$

Given that the vertical line $l$ passes through the point $(2,3)$

Which implies that the equation of line $l$ is $x=2$

Given that the horizontal line $m$ passes through the point $(-1,6)$

Which implies that the equation of line $l$ is $y=6$

Therefore the point of intersection of lines $l$ and $m$ is $(2,6)$
