<u>Answer: </u>
The equation of the circle with center (0, 1) and a radius of 10 is
<u>Solution: </u>
Equation of circle whose center (h, k) and radius r is given as,
---- eqn 1
From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.
Hence we get, h = 0 ; k = 1; r = 10
By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as
On Simplifying we get
Expand using the formula
Hence equation of the circle with center (0, 1) and a radius of 10 is
Answer:
(-5, -7) and the x-axis
Step-by-step explanation:
when looking for a point that is 7 points away, we are looking for a difference of 7 in either the x-value or the y-value.
[remember: a point is written as (x, y) ]
We know that the x-value is -7, meaning that it is 7 units under the x-axis (meaning that it is 7 units away)
We know that our point, (2 , -7) has the same y-value as (-5, -7), so we are looking for a change in x. The difference (which is the change) between:
-5 and 2 is 7
(2 - (-5) = 2 + 5 = 7)
so, both the x-axis and the point (-5, -7) are 7 units away from (2, -7)
(the other point (-7, 7) is not near (2 , -7) at all--they have a larger difference on both the y-values, the x-values, and the length of if you made a diagonal line)

hope this helps!!
