Equation of circle is (x-h)²+(y-k)²=r²
- x²+y²-2x-8=0
- x²-2x-8+y²=0
- x²-2x+1-9+y²=0
- (x-1)²+y²-9=0
- (x-1)²+(y-0)²=9
- (x-1)²+(y-0)²=3²
Radius=3
Centre (1,0)
Option A and D are correct
Answer:
-2
Step-by-step explanation:
The decimal moves forward as many places as there are zeros when you divide a number by 10, or a multiple of 10.
7 divided by 10= .7
7 divided by 100= .07
7 divided by 1000= .007
The slope would be:
-5--3/3-1
-2/2
-1
Slope = -1
