After moving 5 units up, 3 units right, and 4 units down, the ending position is (9, 6). What was the starting position.

You reverse what you did, so first you go 5 units down which makes the coordinates (9,1) then you move 3 units left which then is (6,1). Then you go 4 units up which lets you end out at (6,5).

Answer:

BC = 5

Step-by-step explanation:

Of course, this geometry program can tell you the length of BC.

If you follow directions, you get a right triangle BCF that has leg lengths 3 and 4. The Pythagorean theorem then tells you the length of hypotenuse BC is ...

BF = 4 -1 = 3

FC = 4 -0 = 4

BC² = BF² +FC²

BC² = 3² +4² = 9 +16 = 25

BC = √25

BC = 5
