How do I construct a best-fit line? Begin by plotting all your data.Draw a shape that encloses all of the data, (try to make it smooth and relatively even).Draw a line that divides the area that encloses the data in two even sized areas.Congratulations!

The line of best fit does not have to go through the origin. The line of best fit shows the trend, but it is only approximate and any readings taken from it will be estimations.

Federal Income Tax (FIT) is calculated using the information from an employee's completed W-4, their taxable wages, and their pay frequency. Based on Publication 15-T (2022), Federal Income Tax Withholding Methods, you can use either the Wage Bracket Method or the Percentage Method to calculate FIT.

$9,300 x 15% (rate from the same line in the table) = $1,395. $1,395 + $1,700 (base amt plus) = $3,095. Divide this amount by the number of pay periods in the year to calculate the amount of federal tax to withhold from each pay period. $3,095 divided by 52 (pay periods in the year) = $59.52.

A line of best fit, also called a trend line or linear regression, is a straight line drawn on a graph that best represents the data on a plot. This line passes through some of the points, all of the points, or none of the points. It can be used to make predictions or to show trends in data.

Forcing the best-fit through the origin not only artifically steepens the graph's slope, but it obscures the physically meaningful y-intercept. It's perfectly acceptable, and sometimes desirable, not to begin an axis at zero.

A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line. It is used to study the nature of relation between two variables.

A line of best fit is a straight line that minimizes the distance between it and some data. The line of best fit is used to express a relationship in a scatter plot of different data points.

The taxable wage is determined by subtracting any non-taxable wages, deductions, and employer-provided benefits from the gross wage.

The line of best fit can also tell us about the correlation between two variables. For example, we can tell if the variables x and y have: Positive correlation (as x increases, y also increases). Negative correlation (as x increases, y decreases).
