What is the equation of the line in slope intercept form perpendicular to the y axis and has the point (-4,5)
tatiyna

Answer:

y=5

Step-by-step explanation:

If it is perpendicular to the y-axis, that means it is a horizontal line so the slope m=0.

Use the equation

y-y=m(x-x)

y-5=0(x-(-4))

y-5=0

y=5

The equation of a circle is
sergij07 [2.7K]

Answer:

The answer is

<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>

Step-by-step explanation:

The general equation of a circle is given by

<h3>x² + y² + 2gx + 2fy + c = 0</h3>

where the center of the center of the circle is given by

<h3>( - g , - f)</h3>

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

<h3>( - 7 , - 1)</h3>

The radius of a circle is given by

r =  \sqrt{ {g}^{2}  +  {f}^{2}  - c}

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

r =  \sqrt{ {7}^{2}  +  {1}^{2} - 14 }  \\ r =  \sqrt{49 + 1 - 14}  \\ r =  \sqrt{36}

we have the final answer as

<h3>radius = 6</h3>

Hope this helps you
