How to Find the Equation of a Line: 8 Steps. - wikiHow.
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.
How To: Given the graph of a linear function, write an equation to represent the function. Identify two points on the line. Use the two points to calculate the slope. Determine where the line crosses the y-axis to identify the y-intercept by visual inspection. Substitute the slope and y-intercept into slope-intercept form of a linear equation.
Write the equation for a linear function from the graph of a line Recall that in Linear Functions, we wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely.
