Answer:
The answer to your question is Ф = 45°
Step-by-step explanation:
Data
A (1, 4)
B (-1, 2)
Process
1.- Find the slope of the line
formula
m = ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
Substitution
m = ![\frac{2 - 4}{-1 - 1} = \frac{-2}{-2} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B2%20-%204%7D%7B-1%20-%201%7D%20%3D%20%5Cfrac%7B-2%7D%7B-2%7D%20%3D%201)
Slope definition, is the steepness of a line and also is the tangent of the angle of the line.
tangent Ф = slope
tangent Ф = 1
Ф = tangent⁻¹ 1
Ф = 45°
