Ineed 1. a triangle has vertices at a(−7, 6), b(4, 9), c(−2, − 3). what are the coordinates of each vertex if the triangle is translated 4 units right and 6 units down? 1. a′(−3, 12), b′(8, 15), c ′(2, 3) 2. a′(−11, 0), b′(0, 3), c ′(−6, − 9) 3. a′(−3, 0), b′(8, 3), c ′(2, − 9) 4. a′(−11, 12), b′(0, 15), c ′(−6, 3)

The answer is C. Translating 4 units right would make you "add" 4 units to your x and translating 6 units down would make you "subtract" 6 units to your y. 
A(-7,6) so adding 4 to the x would give you -3, and subtracting 6 to the y would give you 0. -> (-3,0)
B(4,9), add 4 to the x would give you 8, subtract 6 would give you 3. -> (8,3)
C(-2,-3), add 4 to the x would give you 2, subtract 6 would give -9. -> (2,-9)
