Write the equation of the line that is perpendicular to the x-axis and passes through the point (3, 2).

Expert Answers

An illustration of the letter 'A' in a speech bubbles

Hello!

Any (straight) line perpendicular to the x-axis has the equation of the form `x = a,` where `a` is a constant. In other words, for all points of such a line the x-coordinate is the same (and is equal to `a` ).

Therefore if the line must go through the point `(3, 2),` whose x-coordinate is `3,` then its equation is `x = 3.`
