Find the Equation of a Line Given That You Know Two Points.
When a linear association is shown by a scatter plot, we can use a line to model the relationship between the variables. A trend line is a straight line that comes closest to the points on a scatter plot. We can use two points on a trend line to write an equation in slope-intercept form for the trend line. Example 1: Lily is getting trained for a 10K race.
One of the major applications of slope intercept form equation of a line is, it can be used as linear cost function in business. Linear cost function is the function where the cost curve of a particular product will be a straight line. Mostly this function is used to find the total cost of 'n' units of the products produced.
