A line containing the points (9, 1) and (5, 5) intersects the x -axis at what point?
Troyanec [42]

Answer:

It intersects the x-axis at x = 10

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (5 - 1)/(5 - 9)

m = 4/-4

m = -1

y = -x + b

Step 2: Find <em>b</em>

5 = -5 + b

b = 10

Step 3: Rewrite equation

y = -x + 10

Step 4: Find <em>x</em> when <em>y</em> = 0

0 = -x + 10

-10 = -x

x = 10

So the graph crosses the x-axis at 10.

Find the center and radius of the circle. Show all work
Alona [7]

The center is (-1, -2) and the radius of the circle is 5.

<h3>What is the equation of a circle?</h3>

The circle equation formula refers to the equation of a circle which represents the center-radius form of the circle.

A circle can be represented as;

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

Where; h and k are the center of the circle r is the radius of the circle.

The given equation of the circle is;

\rm (x+1)^2+(y+2)^2=25

Comparing both the equations;

\rm (x+1)^2+(y+2)^2=25\\\\\rm (x+1)^2+(y+2)^2=5^2\\\\h = -1\\\\k = -2\\\\r^2=5^2\\\\r=5

Hence, the center is (-1, -2) and the radius of the circle is 5.
