Write the equation of each circle given its center and a point P that it passes through

Elan Coil [88]

Answer:

$(x-1)^2+(y-1)^2=37.$

Step-by-step explanation:

If the center of the circle is (1,1) and the circle passes through the point (2,-5), then the radius of the circle is

$r=\sqrt{(1-2)^2+(1-(-5))^2}=\sqrt{1+36}=\sqrt{37}.$

The equation of the circle with center $(x_0,y_0)$ and radius r is

$(x-x_0)^2+(y-y_0)^2=r^2.$

In your case, the equation is

$(x-1)^2+(y-1)^2=37.$

y = kx is the formula for direct variation

8 = k*20

divide by 20

8/20 =k

divide by 4

2/5 =k

y = 2/5 x

formula: y = 2/5x

b) y=2/5x

y = 2/5 *7

y = 14/5

or as a mixed number 2 4/5
