Answer:

The results are given by:___________.

the equation, y = ax+b.

where a = the slope of the line and b is the intercept or the value of Y when X = 0.

Step-by-step explanation:

The simple linear regression is a model for estimating the relationship that exists between an independent variable and a dependent variable. The model uses a straight line for two quantitative variables. With a scatter graph, the line of best fit is given as the equation, y = bX + a. This equation determines the values of b and a for a dataset of two variables. It can also be used to estimate the value of Y for a given value of X.
