Urse 3: CA > Chapter 4: Graphing Proportional Relationships > Section Exercises 4,3 > Exercise 12 The graph relates the temperature change y (in degrees Fahrenheit) to the altitude change in thousands of feet)
Altitude Change
1 2 3 4 5 7 8 9 10
-5
.
-15
-20
-30
Altitude (thousands of feet)
a. Choose the statement that best explains why the relationship is or is not proportional
The relationship is proportional because the line passes through the origin
12
The relationship is proportional because the line has a negative slope
©
The relationship is not proportional because the line passes through the origin
The relationship is not proportional because the line has a negative slope
b. Write an equation of the line interpret the slope
The equation of the line is y-The slope indicates that the temperature decreases by 'F for each foot increase in altitude
c. You are at the bottom of a mountain where the temperature is 74'F. The top of the mountain is 5500 feet above you What is the temperature at the top of the mountain?
The temperature at the top of the mountain is "F
