Question
The inclination of the line x – y + 3 = 0 with the positive direction of x-axis is ______.
Options
45°
135°
– 45°
–135°
Solution
The inclination of the line x – y + 3 = 0 with the positive direction of x-axis is 45°.
Explanation:
The equation of the line x – y + 3 = 0 can be rewritten as y = x + 3
⇒ m = tan θ = 1
Hence θ = 45°.
