Day 37 Beginner line of the best fit

Introduction In this presentation, we are interested representing data for two variables (called binomial variables) whose relation may appear to be linear. Since our interest in a linear relation, we seek to find the algebraic representation (an equation) for the data plotted.

Vocabulary: Scatter plot It is a graph composed of points representing the relationship between data of two related variables Line of the best fit It is the line in a scatter plot that best represents the points plotted This can be done in the notebooks or on vocabulary cards. Whatever system you use 

x 1 2 3 4 5 6 7 8 9 10 y 12 11 14 17 16 23

Solution Upon drawing the line of the best fit, we have We then draw the line of the best fit and identify two points lying on it.

homework Given the graph below, determine the slope-y intercept form of the equation of the line of the best fit.
