Find the equation of the circle with a diameter whose end points are (-1,-2) and (-3,2)

Sergeeva-Olga [200]

Answer:

The equation of the circle with a diameter whose end points are (-1,-2) and (-3,2) is

$x^{2} +y^{2}+4x-1=0$

Step-by-step explanation:

Explanation:-

Step 1:-

The equation of the circle having center and radius is

$(x-h)^2+(y-k)^2=r^2$

here center is (h,k) and radius is r

Given diameter whose end points are (-1,-2) and (-3,2)

The diameter of the circle is passing through the center of the circle

so center of the circle = midpoint of two end points

$(\frac{-1 +(-3) }{2} ,\frac{-2+2 }{2} )$

$(-2,0)$

therefore center (h,k) = (-2,0)

Step 2:-

we have to find the radius of the circle

the radius of the circle = the distance from center to the one end point

i.e., C P = r

Given one end point is P(-3,2) and center C(-2,0)

The distance formula of two points are

$\sqrt{(x_{2}-x_{1} ) ^{2}+ (y_{2}-y_{1} ) ^{2}}$

$r=\sqrt{{(-3)-(-1) ) ^{2}+ (2-(-2)) ^{2}}$

$r=\sqrt{5}$

Step 3:-

center (h,k) = (-2,0) and

radius $r=\sqrt{5}$

The standard form of circle equation

$(x-h)^2+(y-k)^2=r^2$

$(x-(-2))^2+(y-0)^2=\sqrt{5} ^2$

on simplification is

$x^{2} +y^{2}+4 x-1=0$

I forgot how to divide fractions properly. please send help.

Mamont248 [21]

Answer:

2.5 or 10/4

Step-by-step explanation:

2÷4/5

Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,

2/1÷4/5

But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)

2/1×5/4

And tadaa! you get your answer

10/4

You can also simplify it!

5/2

Which equation describes this graph?

Slav-nsk [51]

Answer:

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-9)/(-3-2)

m=10/-5

m=-2

y=-2x+b

9=-2*-3+b

9=b+6

b=3

y=-2x+3
