s′t′u′v′ is a dilation image of stuv. which is the correct description of the dilation?
a) an enlargement with scale factor 4
b) a reduction with scale factor 4
c) a reduction with scale factor 1/4
d) an enlargement with scale factor 1/4

a reduction with scale factor 1/4

Step-by-step explanation:

Let the distance between the two points be 1 unit

So, Length of ST = 4 units

Length of S'T' = 1 unit

Scale factor =

Scale factor =

So, the scale factor is

So, STUV is reduced by scale factor to obtain S′T′U′V′

So, Option C is true : a reduction with scale factor 1/4

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
