Answer: second option.
Step-by-step explanation:
The equation of the circle in "Standard form" or "Center-radius form" is the following:
Where the center of the circle is at the point (h, k) and the radius is "r".
In this case you have the following equation of the circle written in Standard form:
You can identify that:
Therefore, the center of the given circle is at this point:
Answer:
The slope is 2 and the y-intercept is -6
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to
where
m is unit rate or the slope of the linear equation
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have
therefore
the slope is equal to
and
<u><em>Verify</em></u>
For x=0
---> is ok
