Alright, it went 1 to the right and down 2 times.
So for point B, you calculate the opposite.
Point B goes 1 left while going up by 2.
(9 - 1, 3 + 2) = (8, 5)
Pre-image point A is (8, 5)
Given expression: 3x+9
Take 3 outside from the expression, we get,
= 3(x+3), which is called the equivalent expression
27
you multiply .30 times 90 and you get 27
