Answer:

(x)^2 + (y)^2 = 4^2

Step-by-step explanation:

The standard form of an equation  for a circle is

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

where (h,k) is the center and r is the radius

Since the center is 0,0  and the radius is 4

(x)^2 + (y)^2 = 4^2

Answer:

x^2+y^2=16

Step-by-step explanation:

x^2+y^2=r^2 is the mother function of the equation of a circle centered at r with radius r

since r is defined to be 4 and 4^2 is 16 therefore, the equation would then be

x^2+y^2=16

Find the slope of the line (4,5),(-3,-1)
koban [17]

Step-by-step explanation:

{ \rm{slope =  \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }} \\

• y2 → -1

• y1 → 5

• x1 → 4

• x2 → -3

{ \tt{slope =  \frac{ - 1 - 5}{ - 3 - 4} }} \\  \\ { \tt{slope =  \frac{ - 6}{ - 7} }} \\  \\ { \boxed{ \tt{ \: slope =  \frac{6}{7} }}}
