In the equation y=mx+b, is b the y intercept or x intercept? How can you use data to predict data? Where is the intersection of an x-variable and a y-variable located? What is a slope? What does each variable in the equation of the line of best fit represent?

What does each variable in the equation of the line of best fit represent? Where were those variables located on the graph when you plotted the points? What is the slope of a line used for and where/how is it found? What is the line of best fit used for and where/how is it found? What is the equation for the line of best fit? When playing this game you had to plot points to determine the slope of a line - what is slope? Does the line of best fit have to touch every dot, or does it just fit through most dots?
