Write the equation of the circle in standard form if the points (3,5) and (-5,-1) are endpoints of the diameter

The equation of the circle in standard form if the points (3,5) and (-5,-1) are endpoints of the diameter is

Step-by-step explanation:

Let AB be the Diameter and the end points be

point A( x₁ , y₁) ≡ ( 3 , 5)

point B( x₂ , y₂) ≡ (-5 , -1)

A circle is given as AB is a Diameter.

To Find:

Equation of the circle in standard form = ?

Solution:

Diameter form of the equation of the circle is

(x - x₁)(x - x₂) + (y - y₁)(y - y₂ ) = 0

Where ( x₁ , y₁) and ( x₂ , y₂) are the endpoints of the diameter.

So on substituting the value we get the required equation of circle

(x - 3)(x - (-5)) + (y - 5)(y - (-1)) = 0

∴ (x - 3)(x + 5) + (y - 5)(y + 1) = 0

Applying Distributive property we get

The equation of the circle in standard form if the points (3,5) and (-5,-1) are endpoints of the diameter is

(x, y)→(x − 8, y − 7)

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
