Answer:
The pre-image is the point (0,11)
Step-by-step explanation:
we know that
The rule of the translation is equal to
pre-mage------> image
(x,y) -----> (x+1,y-4)
so
we have that
(x+1,y-4)=(1,7)
so
x+1=1 -----> x=1-1=0
y-4=7 ----> y=7+4=11
therefore
The pre-image is the point (0,11)
Answer:
Step-by-step explanation:
Answer: or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that (second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)
