Question

The equation of the line passing through (4, – 6) and makes an angle $45 ^ { \circ }$ with positive x–axis, is.

• A. $x - y - 10 = 0$
• B. $x - 2 y - 16 = 0$
• C. $x - 3 y - 22 = 0$
• D. None of these

Answer 1

Answer: (A)

$x - y - 10 = 0$

Answer 2

The required equation is

$y + 6 =$ $\tan 45 ^ { \circ } ( x - 4 )$

$\Rightarrow x - y - 10 = 0$.
