Which relationship between x and y in the equation shows a proportional relationship? y= 4x + 2
y = x - 2
y = 8x
y = 1 + 2

y = 8x

Step-by-step explanation:

A proportional relationship has the form

y = kx ← k is the constant of proportion

The only equation in this form is

y = 8x

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
