It looks like the equation relating the temperature (T, the dependent variable) and the altitude (A, the indepedent variable) would be:
T+=+%28-2A%2F1000%29%2B15
Let's check:
T+=+%28-2A%2F1000%29%2B15 Substitute A = 0.
T+=+%28-2%280%29%2F1000%29%2B15
T+=+15 OK.
T+=+%28-2A%2F1000%29%2B15 Substitute A = 1000.
T+=+%28-2%281000%29%29%2F1000%29%2B15
T+=+-2%2B15
T+=+13 OK.
T+=+%28-2A%2F1000%29%2B15 Substitute A = 3000.
T+=+%28-2%282000%29%2F1000%29%2B15
T+=+-4%2B15
T+=+11OK.
T+=+%28-2A%2F1000%29%2B15 Substitute A = 5000.
T+=+%28-2%285000%29%2F1000%29%2B15
T+=+-10%2B15
T+=+5
So the predicted temperature at an altitude of 5000 feet would be 5 degrees C.
