We suspect that 'A' is not equal to 7 9, but that (7, 9) are
the coordinates of 'A'. Same for 'B'.
If that's true, then the two points are 5 units apart.

If you mean endpoints of (-1, -3) and (11, -8) then the length works out as 13
Draw the circle O, and the chord AB. From the center, draw the radius OC which passes though the midpoint, D, of AB. Since the radius OC bisects the chord AB, it is perpendicular to AB. So that CD is the required height, whose length equals to the difference of the length of the radius OC and the length of its part OD. Draw the radius OA and OB. So that OD is the median and the height of the isosceles triangle AOB, whose length equals to √(r2 - AB2/4) (by the Pythagorean theorem). Thus, the length of CD equals to r - √(r2 - AB2/4).
To find the length of segment AB, we can use the segment addition postulate, which states that the total length of a segment is equal to the sum of the lengths of its parts. Therefore, AB + BC = AC. Given that AC = 78 mm and BC = 29 mm, we can substitute these values into the equation to find AB: AB + 29 = 78. Solving for AB, we get AB = 78 - 29 = 49 mm.

It would be a straight line of length bc
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
End points: (-2, -4) and (-8, 4) Length of line AB: 10
That is correct. The distance from a point C to a line AB is the length of the perpendicular segment drawn from point C to line AB. This forms a right angle, creating a right triangle with the segment as the hypotenuse. The length of this perpendicular segment is the shortest distance from the point to the line.

Using the distance formula the length of ab is 5 units
