Jean transformed a point by using the rule (x, y) right-arrow (x minus 6, y + 8). The image point is (–4, 1). Which point is the pre-image? a-(–10, 9)
b-(2, –7)
c-(–2, 7)
d-(10, –9)

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
