The coordinates of triangle symbol DEF are Upper D left parenthesis 3 comma 4 right parenthesis, Upper E left parenthesis 7 comma 4 right parenthesis, and Upper F left parenthesis 5 comma 9 right parenthesis. If you translate triangle symbol DEF 3 units left and 2 units up, what are the coordinates of Upper Eprime?
To find the coordinates of E', we will simply subtract the translation values from the original coordinates of E.
Original coordinates of E: (7, 4)
Translation: 3 units left and 2 units up
New coordinates of E': (7 - 3, 4 + 2)
New coordinates of E': (4, 6)
Therefore, the coordinates of E' are (4, 6).
