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)

c.

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
