Step-by-step explanation:
I'll graph the line on desmos.
We get this vector, check first picture
First, we need to find x and y componets.
To do that, we find the displacement between the points
Since R is inital, the horinzontal displacement is. 3.
Since R is inital, the vertical displacement is -6. So
our x and y components is (3,-6).
We then using tangent to find direction angle
[tex] \tan(x) = \frac{ - 6}{3} [/tex]
[tex] \tan(x) = - 2[/tex]
[tex]x = 116.57[/tex]
So our direction angle is 116.57 degrees.
