Answer:
C
Step-by-step explanation:
The elevati0on of sea level is 0 km and the elevation of the summit is 10 km
y=10+x(0.5)
This is the way of writing that equation.
Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3
