Subtract 2 and 1
subtract 9 and 3
then divide
so it would be 2-1=1
9-3=6 then your answer is 6
You find three times that number.
I'm pretty sure y=6, but I would take caution.
The vertices of triangle QRS have coordinates Q(1, −2), R(3, −2), and S(2, −4). The coordinates are the coordinates of the vertices of triangle QꞌRꞌSꞌ when triangle QRS is reflected across the x-axis <span>Qꞌ(1, 2), Rꞌ(3, 2), Sꞌ(2, 4). The answer is letter B.</span>
