What is the equation of the line?

y= -2x+8

Step-by-step explanation:

y= mx +b

m is the slope and here is m= -8/4 = -2

b is the y-intercept and here is 8

y= -2x+8

i found two solutions,   n = 2 • ± √3 = ± 3.4641

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
