Question

The line $ax+by=ab$, will meet the x- axis at _____.

• A. $(a,0)$
• B. $(0,a)$
• C. $(0,b)$
• D. $(b,0)$

Answer 1

The correct option is D $(b,0)$

The y-coordinate of the point at which the line meets the x- axis will be zero.

Substituting y = 0 in
$ax+by=ab\to ax=ab\to x=b$

The line $ax+by=ab$ meet the x- axis at $(b,0)$
