The radius of the circle whose equation is (x-3)^2 + (y+1)^2 = 16 is

Firdavs [7]

Answer:

Step-by-step explanation:

The general equation of a circle with center (a, b) and radius r is given by the equation;

$(x-a)^{2}+(y-b)^{2}=r^{2}$

The constant in the right hand side of the equation is simply the square of the radius;

We have been given the following equation;

(x-3)^2 + (y+1)^2 = 16

Comparing this with the general equation above;

$r^{2}=16\\\\r=\sqrt{16}=4$

If you are givent two points on a line, (5,6) and (-5, -4), what is the slope of the line!

alexira [117]

Answer:

m = -1

Step-by-step explanation:

Formula we'll use: $\frac{y2}{x2} -\frac{y1}{x1} =m$

m = slope.

y2 = -4

x2 = -5

y1 = 6

x1 = 5

Substitute -4, -5, 6, 5 into the formula:

$\frac{-4}{-5} -\frac{6}{5} =$

Subtract both top and bottom:

m = -10/-10

m = -1
