Answer:
Equation of circle in standard form with centre (0, – 10) and radius 6.
Step-by-step explanation:
We need to write equation of circle in standard form with centre (0, – 10) and radius 6.
The equation of circle is:
where (h,k) is centre of circle and r is radius
We are given centre (0,-10) so, h=0, k=-10 and radius r = 6
Putting values and finding equation:
So, equation of circle in standard form with centre (0, – 10) and radius 6.
Answer:
Step-by-step explanation:
Looking at the graph
For x=-2 ---> f(x)=3
For x=2 ---> f(x)=1
so
we have the points
(-2,3) and (2,1)
Find the slope
The equation of the line in slope-intercept form is equal to
we have
---> see the graph
