Find the center of a circle with the equation: x^2 + y^2 - 2y - 8x - 19 = 0
777dan777 [17]

Answer:

(4, 1)

Step-by-step explanation:

x^2 + y^2 - 2y - 8x - 19 = 0

We rearrange the terms and complete the square twice.

x^2 - 8x + y^2 - 2y = 19

x^2 - 8x + 16 + y^2 - 2y + 1 = 19 + 16 + 1

(x - 4)^2 + (y - 1)^2 = 6^2

The center is (4, 1)

Y= -2x-21<br> determine the intercepts of the line
puteri [66]

Answer:

The y-intercept is -21. The x-intercept is -10.5 or -\frac{21}{2}.

(0, -21) and (-10.5, 0)

Step-by-step explanation:

To find the y-intercept, you would plug in 0 for x.

y = -2x - 21

y = -2(0) - 21

y = 0 - 21

y = -21

The y-intercept is -21.

To find the x-intercept, you would plug in 0 for y.

y = -2x - 21

0 = -2x - 21

2x = -21

x = -21/2

x = -10.5 or -\frac{21}{2}

The x-intercept is -10.5 or -\frac{21}{2}.
