One of the points on the previous graph is the ordered pair (6, $15). What does that point represent? How can you use that ordered pair to find the unit rate, or constant of proportionality?

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

y = -1

x = 8

hope this !
