For a ground temperature of 15 degree Celsius, the air temperature (t) at an altitude of 500m (h) is 10 degree Celsius. At 2000 m, the air temperature is 5 degree Celsius. Use the ordered pairs (h,t).
a. Find a linear equation for these data points.
b. Use this linear equation to find the air temperature at 1500m.

Best ResponseYou've already chosen the best response.1You have been given two ordered pairs: (500,10) and (2000,5) Can you find the slope of this line?

Best ResponseYou've already chosen the best response.1Subtract the second numbers of the ordered pairs: 10(5)=15 Subtract the first numbers of the ordered pairs: (5002000)=1500 Put the first number over the second: 15/1500 =1/100 That is the slope.

Best ResponseYou've already chosen the best response.1Now substitute the slope and one of the ordered pairs into y = mx + b and find b. Then you will have the equation of your line.

Best ResponseYou've already chosen the best response.0can you pick either one (15/1500) or (1/100) as the x and the y?

Best ResponseYou've already chosen the best response.11/100 is m, the slope. For x and y you may use either ordered pair you choose.

Best ResponseYou've already chosen the best response.0I got 15 = (1500)(1/100) + b

Best ResponseYou've already chosen the best response.1\[10=\frac{1}{100}(500)+b\] \[10=5+b\] \[15=b\]
