Linear equations increase by a constant slope, but exponential equations increase by a constant exponent or power. For example, y = 2x + 1. It starts from 1 and each x is multiplied by 2. On the other hand, exponential equations of form y = x^2 increase each x by the power of 2.

When considering a simple linear regression model, it is important to check the linearity assumption -- i.e., that the conditional means of the response variable are a linear function of the predictor variable. Graphing the response variable vs the predictor can often give a good idea of whether or not this is true. readymade community centre
