Answer:
y = − (7 /2) x + 60 equation could represent the line of best fit for the temperatures, in degrees Fahrenheit, based on the altitudes, in thousands of feet
Step-by-step explanation:
Given:
A plot for temperature and altitude
(Refer the attachment) .......FOR GRAPH
To Find:
Correct relationship between them
Solution:
By using given relationship as we can conclude.
1)y=-5x+70:
Put y=0 then
5x=70
x=70/5
x=14
This value dont corresponds when y=0 in graph
2) y=-10x+70
put y=0 then
10x=70
x=7
This value dont corresponds when y=0 in graph very less than original value.
3)y=-(7/2)x+60
put y=0 then
(7/2)x=60
7x=120
x=120/7
x=17.14
This value corresponds when y=0 in graph
4)y=-(9/2)x+60
Put y=0 then
(9/2)x=60
9x=120
x=120/9
x=13.33
This value dont corresponds when y=0 in graph which much less than original value.
