If the triangle is translated left 9, this shows that all the x values will decrease by nine, becoming, -15, -5, and -8.
If the triangle is translated up 12, this shows that all the y values will increase by twelve, becoming, 13, 12, and 15.
Thus, the new co-ordinates are <u>X(-15,13), Y(-5,12), Z(-8,15).</u>
