It is 8 units because if you start at -5,2 you will have to go up 8 units to get to -5,10. They are 8 units away from each other.
Answer:
(5,-3) , (10, -2), (7,-8)
Step-by-step explanation:
The new triangle will be
(5,-3) , (10, -2), (7,-8) by mapping
(x,y) => (x +3, y-5)
Ok 1st for the triangles you multiply the base X height then multiply by two. For EX: 5x10=50/2=25 so that's the answer for your first triangle.
