Question 1089601: Two circles with center A and B are tangent to each other and both tangent to the x axis in the xy coordinate place. If circle A has a radius of 1 and circle B has a radius of 4, what's the slope of the segment that connects both center? Answer by ikleyn(52852) (Show Source):
Make a sketch.
Find and draw a right angled triangle in your sketch.
(1 + 4) = 5 is the length of the hypotenuse of the right-angled triangle.
(4 - 1) = 3 is the length of the vertical leg.
You need to find the length of the horizontal leg.
The slope is = = = = = .
