How is the distance from the sun for planets in our solar system related to the mean temperature of each planet? to find out, sc
Verdich [7]

Based on the data shown by the scatterplot on the distances in the solar system, a. an exponential model is appropriate because the scatterplot relating distance to temperature is curved.

<h3>Why is an exponential model appropriate?</h3>

The usage of the natural log to transform some of the variables resulted in the scatterplot of temperature v. distance ratio being curved.

As a result, a linear model cannot be used. The best model will therefore be an exponential model which is best for curves in a scatterplot.
