Answer:

a) y-coordinates

b) undefined

c) x=8

d) y= x-6

e) y= -2x+9

2. y=6x+17

Step-by-step explanation:

2. y=mx+b use point (-2,5) and slope to find b

5=6(-2)+b

5=-12+b

5+12=b

b=17

y=6x+17

The diagonals of quadrilateral EFGH intersect at D(?3,4). EFGH has vertices at E(3,7) and F(?4,5). What must be the coordinates

Katen [24]

Answer:

G(3, 1), H(2, 3)

Step-by-step explanation:

When D is the midpoint of EG, it means ...

D = (E + G)/2

G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)

Likewise, H is ...

H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)
