Graph It!



1. Graph the following circles on one set of coordinate axes:

x2 + (y - 6)2 = 16
(x - 9)2 + (y - 6)2 = 16
(x + 9)2 + (y - 6)2 = 16
(x + 4.5)2 + (y - .5)2 = 16
(x - 4.5)2 + (y - .5)2 = 16


2. Graph the following on one set of coordinate axes:

x2 + (y - 7)2 = 64         :     7 y
(x + 6)2 + (y - 7)2 = 4         :     7 y
(x + 2)2 + (y - 7)2 = 4         :     7 y
(x - 6)2 + (y - 7)2 = 4         :     7 y
(x - 2)2 + (y - 7)2 = 4         :     7 y

the point (0, -9)

y = -2x - 9         :     -8 x 0
y = -4x - 9         :     -4 x 0
x = 0         :     -9 y 7
y = 4x - 9         :     0 x 4
y = 2x - 9         :     0 x 8


3. Graph the following on one set of coordinate axes:


y = .5 x2 + 4         :     -4 x 4
x = 3         :     -11 y 8.5
x = -3         :     -11 y 8.5
x2 + (y + 11)2 = 9         :     y -11
y = 2x + 8         :     3 x 6
y = 4x + 8         :     2 x 3
y = -2x + 8         :     -6 x -3
y = -4x + 8         :     -3 x -2
