Question

The angle made by the line with the positive direction of the X-axis is given. Find the slope of the line:

45°

The angle made by the line with the positive direction of the X-axis is 45°. Find the slope of that line.

Answer 1

Using the trigonometric relation between angle and slope:

Since, slope = tan θ

Here, θ = 45°

∴ slope = tan 45°

So, slope = 1

Therefore, the slope of the line is 1.
