Question

△ABC is dilated from the origin by scale factor r=1/4. Draw △A'B'C' and label the vertices with coordinates.

the images triangle is A=(-10,6) B=(-11,2) C=(-4,4)

Answer 1

for each coordinate (x,y) multiply the x and y by 1/4
(x,y) -> (1/4 x , 1/4 y)

Answer 2

mhm

Answer 3

do you understand?

Answer 4

yes i understan that i have to do that but i forgiot hot to multiply it my 1/4

Answer 5

A = (-10,6)

\( A=(-10 * \frac{1}{4} , 6 * \frac{1}{4}) = (\frac{-10}{4},\frac{6}{4})\)
divide numerator and denominator by 2
\[(\frac{-5}{2},\frac{3}{2})\]

Answer 6

do the same with the other coordinates

Answer 7

oh ok thank you so much^_^

Answer 8

yw~

Answer 9

^_^^-^
thank you I really appreciate it

Answer 10

sorry to disturb so i divide everything by 2 or are each of them different

Answer 11

B = (-11, 2), scale factor of 1/4

(x,y) -> (1/4 x , 1/4 y)

so (1/4 * -11, 1/4 * 2)
= (-11/4 , 2/4)
can you simplify the x or the y value?

Answer 12

that is what i am confused about I dont know how to do that

Answer 13

I was thinking -7,2 but i dont know if it is right
