Which equation represents a circle with a center at (-3,-5) and a radius of 6 units?
(x - 3)2 + (1 - 5)2 = 6
(x - 3)2 + (y - 5)2 = 36
(x + 3)2 + (y + 5)2 = 6
(x + 3)2 + (y + 5)2 = 36

(x +3)^2 + (y + 5)^2  = 36

Step-by-step explanation:

Use general circle equation:

(x - h)^2  + (y - k)^2  = r^2

center:  (h, k)

radius : r

(x - (-3))^2 + (y - (-5))^2  = 6^2

(x +3)^2 + (y + 5)^2  = 36

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: y = -2.5x - 15
