If the center of a circle is at
(-7,9) and its radius is 5, complete
its equation:

The answer is

Step-by-step explanation:

Equation of a circle is written as

( x - a)² + ( y - b)² = r²

where r is the radius and a and b are the center of the circle

The center of the circle is ( - 7 , 9)

Radius is 5

Substituting the values into the equation we have

( x - - 7)² + ( y - 9)² = 5²

We have the final answer as

Hope this helps you

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
