Question

Find the inclination of a line whose slope (gradient) is 1.

Answer 1

If tan θ is the slope of a line, then the inclination of the line is tan θ.

Here, the slope of a line is 1, then tan θ = 1

Now,

tan θ = 1

tan θ = 45°

∴ θ = 45°

Hence, the inclination of the given line is θ = 45°.
