6.4 Fit Line To Data

Section 6.4 Fit Data to a Line

A1.3.1 Write an equation of a line when given the graph of the line, a data set, two points on the line, or the slope and a point of the line;

A1.3.2 Describe and calculate the slope of a line given a data set or graph of a line, recognizing that the slope is the rate of change;

A1.3.3 For bivariate data that appear to form a linear pattern, find the line of best fit by estimating visually and/or using appropriate technology to determine the least squares regression equation. Interpret the slope of the equation for a regression line within the context of the data and use the equation to make predictions;

A1.5.2 Approximate a line of best fit (trend line) given a set of data (e.g., scatterplot). Use technology when appropriate;
