Atriangle is drawn on the coordinate plane. it is translated 4 units right and 3 units down. which rule describes the translation?

(x ,y) →→ ( x + 4  , y - 3 ) .

Step-by-step explanation:

Given  : A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down.

To find : Which rule describes the translation.

Solution : We have given  

A triangle is translated 4 units right and 3 units down.

By the rule of transformation : A vertical translation of b units transforms the coordinates (x, y) into:

x' = x  

y' = y + b

A horizontal translation of a units transforms the coordinates (x, y) into:

x' = x + a

y' = y

Then translated 4 units right and 3 units down

(x ,y) →→ ( x + 4  , y - 3 ) .

Therefore, (x ,y) →→ ( x + 4  , y - 3 ) .

the answer is 28

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
