No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.

The temperature was -4°F this morning. If the temperature dropped 7°F then the temperature now should be -11° fahrenheit.
We have got an equation that can relate these three units of measurement of temperature, as given below:
where C represents the measurement of a fixed temperature in celsius, F represents the measurement of that same intensity temperature in Fahrenheit, and also K represents the measurement of equally intense temperature in kelvin.
Given that the temperature was -4° in the morning. And the temperature dropped 7° later.
We have to Subtract 7 from -4.
-4 - 7 = 11
Thus, The temperature now should be -11°F.
