Answer: √32
Step-by-step explanation: so the displacement is north 4 and west 4 and it becomes a right triangle so the hypotenuse is the distance for segment AB
So Drawn out should like straight lines up,down,left,and right. So east is positive while west is negative same for North(+) and South(-)
I recommend sticking with 2 directions first. Starting with north and south right. First you go south 1 mile but then you go north 5miles in math terms
-1+5=4 or down one is one less than 5
Same for east and west. 3+-7 = -4
So we went positive 4 miles up and 4miles to the left
So (-4)^2+4^2= hypotenuse or AB segment in this case

Answer:
You already have what you are going to substitute, just put the y values from the first equation into the second! Like this:
6x - 5(-2x - 9) = -19
Multiply it out:
6x +10x +45 = -19
Add like terms + simplify:
16x + 45 = -19
16x = -64
x = -4
take that x and put it back into the first equation!!
y = -2(-4) -9
y= 8-9
y= -1
so... your answer is (-4, -1)
hope this helps!
