In order to describe the translation of the triangle ABC we need to know the rule of translation, i.e. we need to know how many units to the left or to the right the x coordinate will move and how many units up or down the y coordinate will move
Apart from Knowing the coordinates of vertices of triangle ,we must know by how much the coordinates of vertices of triangle and in which direction , it is translated.There are four kinds of translation possible
12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.
