First find midpoint:
Find slope of line that passes through R and S: slope =
Negative reciprocal of slope to get slope of perpendicular: new slope = 6
Line will be:
Answer:
y=3
Step-by-step explanation:
y + 3 = –y + 9
Add y to each side
y+y + 3 = –y+y + 9
2y+3 = 9
Subtract 3 from each side
2y+3-3 = 9-3
2y = 6
Divide by 2
2y/2 = 6/3
y =3
15.5 (Just round 15.49 to the nearest tenth)
the airplane new altitude is 17500
20000-2500=17500
