Answer:
Step-by-step explanation:
If the new height is 338m and the helicopter decended 127m to get to that new height then the original height is simply the sum of them both.
H = 338m + 127m
H = 465m
Goes +3
18, 21, 24, 27, 30
Slope can be found but putting the equation in slope intercept form (y=mx+b)
6y=3x-12
y= 0.5x-2
M is your slope, b is the y intercept.
So the slope is 1/2, yintercept is (0,-2)
Hope this helps
