Answer:
The center is (-3,2) and the radius is r=2
Step-by-step explanation:
The general equation of the given circle is

Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;



The quadratic trinomials in x and y on the left side of the equations are perfect squares.
We factor to obtain;


Comparing to:

The center is (-3,2) and the radius is r=2

Answer:
What grade of math is this?
Step-by-step explanation:
Using a calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:
a. y = −1.74x + 46.6
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
For this problem, the points (x,y) are given as follows, from the given table:
(1, 46), (2, 42), (3,40), (4, 41), (5, 38), (6,36).
Hence, inserting these points in the calculator, the equation for the line of best fit where x represents the month and y represents the time is given by:
a. y = −1.74x + 46.6
