Which table represents a linear function?

C

Step-by-step explanation:

in C slope is same

in C slope=(9-7)/(4-2)=2/2=1

or =(11-9)/(6-4)=2/2=1

or =(13-11)/(8-6)=2/2=1

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
