a and b: see graph

c) a - reflection over x axis

b - translation 2 right, 3 up

Circles (double points)

what is the center and radius of this equation: (x+3)^2 + (y-8)^2 = 16

Center: (-3, 8)

Radius:  4

Practice 1 a

Center is (-4,6)

Radius is 7

400

Practice 1 b 

Center (3, -2)

Radius is 4

Lines

10 a just find the slopes

slopes: QR -1, RS 1, ST -1, QT 1

200

10 a find the lengths

QR - sqrt(18), RS sqrt(8), ST sqrt(18), QT sqrt (8)

y = (1/3)x - 5

3

y = 2x - 5

Lines (double points)

9 a & b

a) Yes because it's equidistant from the focus and the directrix (2 units from both)

b) No (you can just eyeball this it's clearly not on the line) plus it's not equidistant from f and d
