write the standard form of the equation of the circle with the graph shown to the right. what is the standard form of the equation of the circle to the right?

Answer

Explanation:

Step1: Identificar el centro

El centro del círculo en el gráfico está en el punto $(-1, - 1)$.

Step2: Determinar el radio

Contando cuadrados en el gráfico, el radio $r = 1$.

Step3: Usar la fórmula estándar

La fórmula estándar de la ecuación de un círculo es $(x - h)^2+(y - k)^2=r^2$, donde $(h,k)$ es el centro y $r$ es el radio. Sustituyendo $h=-1$, $k = - 1$ y $r = 1$: $(x-(-1))^2+(y - (-1))^2=1^2$ que se simplifica a $(x + 1)^2+(y + 1)^2=1$.

Answer:

$(x + 1)^2+(y + 1)^2=1$
