Question

For lines with slope magnitude |m|<1, ?x can be_________

(a) A set corresponding vertical deflection

(b) A set proportional to a small horizontal deflection voltage

(c) Only a

(d) All of the mentioned

I got this question by my school teacher while I was bunking the class.

This intriguing question originated from Line Filling Algorithms topic in division Graphics Primitives of Computer Graphics

Answer 1

Right answer is (b) A set proportional to a small horizontal deflection voltage

For explanation I would say: ?x can be a set proportional to a small horizontal deflection voltage only if slope magnitude |m| < 1.
