The correct options regarding the circle with endpoints of the longest chord at (4, 5.5) and (4, 10.5) are:
- The radius is of 2.5 units.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center 
and radius r is given by:
The center is the <u>midpoint of the chords</u>, hence:
.
.
The radius is half the distance between the chords, hence:
.
Hence the equation is:

Answer:
-1
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(9 - 4) / (1 - 6)
5 / -5
= -1
So, the slope is -1
Answer:
yes
Step-by-step explanation:
They are correct because the reciprocal ( flipped or opposite) of -2/5 is 5/-2
If x=-1 => y-2=5=> y=7,x=-1
If x=0=> y+0=5=> y=5,x=0
If x=3=> y+6=5=> y=-1,x=3
Answer:
0 and 0
Step-by-step explanation:
The only number that can be applied to the expression without changing the sum is 0, for example 5 + 10 = 15, adding 2 0's will be 0 + 5 + 10 + 0 = 15 :D
