Answer 3

That's all that I was given.

Answer 4

ok give me a second.

Answer 5

alright

Answer 6

well the only way i see a numerical answer is if you make up the coordinate points but make them true throughout the rest of the points. so for example you can put

so based on the coordinate grid i can say c=1,1 and b=7,3

Answer 7

then i would go ahead and use

\[distance=\sqrt{(x2-x1)^2+(y2-y1)^2}\]

Answer 8

plug it all in and you get the square root of 40. which rounds to 6.3 to the nearest tenth.

Answer 9

make sense?

Answer 10

That does make sense when you add the coordinates, but is there any way to know that those are the exact coordinates?

Answer 11

Well distance is distance. It wouldn't matter what the exact coordinates are, the distance will always be the same.

Answer 12

I mean if point c was 60,61. as long as you move one point per line point b will end up as 66,63. the distance is the same still if you use the distance formula

Answer 13

\[\sqrt{(66-60)^2+(63-61)^2} = \sqrt{(6^2)+(2)^2}\]

Answer 14

still the square root of 40

Answer 15

Ahh I understand now. Thank you so much for your help!
