Answer:
(5, 4) is correct.
First comes x, which is horizontal on the graph
Then comes y, which is vertical.
12 is the answer
12 goes into all threee
the answer would be 374.00
the original value before any increase or decrease is 340.00
so...
340.00 X 1.10 = 374.00
Length = √(y2-y1)² + (x2-x1)²
l = √(8-8)² + (7+3)²
l = √10²
l = 10
In short, Your Answer would be 10 units
Hope this helps!
