Answer:
Step-by-step explanation:
Let the initial elevation is x.
<u>An airplane descends 2.2 miles to an elevation of 6.75:</u>
Answer: 8.75 miles
Explanation: this is simple, just add the descending variable to the current elevation to get the previous elevation.
Wait what do you mean by this?
y = -x -1
<em><u>Brainliest, please!</u></em>
(4, -5)(-6, 5)
y = mx + b
m = slope, b = y-intercept
m = 10/-10
m = -1
y = -1x + b
We can plug in (4, -5):
-5 = -1(4) + b
-5 = -4 + b
b = -1
y = -x - 1
