Answer:
T(2, -1)
T(1, 2)
Step-by-step explanation:
From (3, 2) to (5, 1), the translation is T(2, -1). x goes up by 2. y goes down by 1.
From (5, 1) to (6, 3), the translation is T(1, 2). x goes up by 1. y goes up by 2.
You can use Substitution to solve this problem:
4x-y=20
-y=-4x+20
y=4x-20
Now you have two equations, and you use the first one to substitute into the second one.
y=4x-20 and -2x-2y=10
-2x-2(4x-20)=10
-2x-8x+40=10
-10x+40=10
-10x=-30
-x=-3
x=3
Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.
4x-y=20 x=3
4(3)-y=20
12-y=20
-y=8
y=-8
<em><u>So your answer would be x=3 and y=-8</u></em>
