Question

@jim_thompson5910 4. Graph the circle with center at (0, 4) and radius 2. Write the equation of the circle.

Answer 1

In this case

h = 0
k = 4
r = 2

Answer 2

can you do the equation for me please :) @jim_thompson5910

Answer 3

start with (x-h)^2 + (y-k)^2 = r^2 and plug in h = 0, k = 4 and r = 2

Answer 4

Tell me what you get

Answer 5

(x-0)^2+(y-5)^2=2^2 @jim_thompson5910

Answer 6

k = 4, not k = 5

Answer 7

oh *y-4

Answer 8

good, and 2^2 = 4

finally x-0 is the same as just x

Answer 9

so

(x-0)^2+(y-4)^2=2^2

turns into

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