Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
Let's write the equation in standard from

Where,
- m is slope or rate of change
- b is the y-intercept or initial value
<h3>Let's start by finding slope⤵️</h3>

- x1, y1 = 0,12
- x2, y2 = 1,13



<h3>Equation⤵️</h3>
