Atransformation of klm results in k’l’m’ which transformation maps the pre image to the image

answer:

dilation

step-by-step explanation:

the triangle retains its congruence in all its angles and side lengths, however the side lengths itself are becoming larger, which suggests dilation.

if it was a translation, the triangle dimensions would be the same.

if it was a reflection, the triangle would be facing the other way.

if it was a rotation, the triangle would be facing how many degrees it has rotated.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
