I graphed the 4 points and connected the dots. (Sorry I'm not able to show this)
I then realized it was some type of trapezoid however, I wasn't sure which kind of trapezoid (regular or isosceles) so I googled the properties of both and concluded that it makes a regular trapezoid.
Since angle 4x and 8x look like supplementary angles 4x+8x=180°. After solving that equation x=15. Plug that number in and 4x=60° and 8x=120°
The slope is -2 because perpendicular is the resipricole to 1/2
