Answer:
m=-2
Explanation:
If a line passes through the points (4,5) and (2,9): to calculate the slope, use the formula below:
Substituting the points, we have:
The slope of this line is -2.
Four tangent circles centered on the x-axis are shown below. The radius of circle A is twice the radius of circle O. The radius
of circle B is three times the radius of circle O. The radius of circle C is four times the radius of circle O. All circles have integer radii. The point (63, 16) lies on circle C. What is the standard equation of circle A? A detailed explanation would be preferred :)
