Question

I need help with this problem !

Answer 1

To find the center of the circle, set the x-component equal to zero and the y-component equal to zero to find the ordered pair.

x+1=0
x=-1

y+2=0
y=-2

The center of your circle will be at (-1, -2).

To find the radius of the circle, square root the 16.

The equation of a circle is x^2+y^2=r^2

So square root the 16 to get your radius, which is 4.

To graph the circle, plot the center of the circle, and plot 4 different points directly out from the center that are 4 units out. Then connect the dots :)

Answer 2

The center is (-1,-2)

the radius is 4
