Question

A ray light passing through point A(–2, 3) & get reflected at point B on x-axis & then passes through point (3, 2) then equation of line AB ?

• A. y – x = 5
• B. y = –x +1
• C. x + y = 2
• D. None of these

Answer 1

Answer: (B)

y = –x +1

Answer 2

Equation of line AB is same as line $\mathrm { AC } ^ { \prime }$

(y – 3) = $\frac { - 2 - 3 } { 3 + 2 }$(x + 2)

y – 3 = – x – 2 Ž x + y = 1
