Question

what translation rule can be used to describe the result of the composition of (x,y) --> (x - 9,y - 2) and (x,y) --> (x + 1, y - 2) ? PLEASE HELPPPPP!!!!!

Answer 1

Move x coordinate 9 units left then y coordinate 2 units upwards

Move 1 unit to the right and 2 units down

Answer 2

we know that

the rule of the translation A is

$(x,y)-----> (x-9,y-2)$

that means

the translation is $9$ units to the left and $2$ units down

the rule of the translation B is

$(x,y)-----> (x+1,y-2)$

that means

the translation is $1$ unit to the right and $2$ units down

therefore

the rule of the composition A+B is

$(x,y)-----> (x-9+1,y-2-2)$

$(x,y)-----> (x-8,y-4)$

that means

the translation is $8$ units to the left and $4$ units down

so

the answer is

$(x,y)-----> (x-8,y-4)$
