What is the center and radius of a circle whose equation is x2 + y2 -2x -6y -5 = 0?
ddd [48]

x²+y²-2x-6y-5=0

x²-2x+y²-6y=5

x²-2x+1+y²-6y+9=5+1+9

(x-1)²+(y-3)²=15

(x-1)²+(y-3)²=(V15)²

-> centre of the circle: C(-1,-3)

-> radius of the circle: V15

Find an equation of the line that goes through the points (-9,-20) and (-8,-17). Write your answer in the form y = m x + b .
Oliga [24]

Answer:

y = 3x + 7

Step-by-step explanation:

First, we will solve for the slope (m).

The formula for slope is: m = \frac{y2 - y1}{x2 - x1}

m = \frac{-17 - -20}{-8 - -9} --- enter the points into the formula

m = \frac{3}{1} --- simplify

m = 3 --- simplify

Now we will solve for the y-intercept (b).

y = mx + b

y = 3x + b --- substitute the slope into the equation

-20 = 3(-9) + b --- substitute the x and y of either point into the equation

-20 = -27 + b --- simplify

7 = b --- add 27 to both sides

b = 7

Done.

y = 3x + 7
