Considering that a scatter plot is a linear function, the best choice is an increasing linear function.
<h3>What is a linear function?</h3>A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
A scatter-plot is the approximation of a linear function, in this problem with the input being the outside temperature and the output being the number of bathing suits. These measures are direct proportional, as they increase together, hence, the best choice for the scatter-plot is an increasing linear function.
