What kind of line is x+y= -10 and x-y = 5

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

yes

step-by-step explanation:

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
