6) The scatter plot below shows the temperatures (y), in degrees Fahrenheit (°F), that were recorded at different altitudes (x), in thousands of feet. Which equation could represent the line of best fit for the temperatures, in degrees Fahrenheit, based on the altitudes, in thousands of feet? A) y = −5x + 70 B) y = −10x + 70 Reactivate C) y = − 7 2 x + 60 D) y = − 9 2 x + 60

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.

irrational, cannot
