Honestly not sure what all the numbers you put down were (numbers for the graph?), but here is how to find the slope :)
First, find two "exact" points!
I am going to use (0, 1) and (2, 2)
We then go to our first point, (0, 1), and count how many points up it is until we are on the same x-axis of our y. This is 1. We then do the same thing for the y-axis. This is 2. It is rise over run, so the answer is
(I hope this helps, have a nice day!)
From the astronaut to the horizon is a tangent line to the curvature of the earth. And from that point on the horizon to the center of the earth is at a right angle to the tangent and is equal to the radius of the earth...so we can say
cosα=r/(r+h) where r is the radius of the earth and h is the height above the surface of the earth...
α=arccos(r/(r+h))
now tanα=d/r where d is the distance from the astronaut to the point on the horizon so:
tan(arccos(r/(r+h))=d/r
d=rtan(arccos(r/(r+h))) and using r≈4000 and h=50 we get:
d=4000tan(arccos(4000/(4050)))
d≈634.42mi
d≈634 mi (to nearest mile)
