The Linear Equation calculator computes the y coordinate on a line (the range) based on the linear coefficients of slope (m) and intercept (b) and the value of x (the domain).
INSTRUCTIONS: Enter the following:
- (m) Slope of Line
- (b) y Intercept
- (x) value of x
Slope Intercept Line Range (y): The calculator returns the value of y corresponding to the x value on the line.
The Math / Science
The slope intercept form of a line is:
y = m⋅x + b

- Least-squares Trend Inference : This is a linear equation used with Linear Regression to compute a predicted value of Y based on X.
- Wilcoxon Signed Rank Test: This provides the Wilcoxon statistics and critical value for two groups of numeric observations based on an alpha value and whether it's a one or two tailed test.
- Slope-Intercept form of a Line: This provides the slope intercept form (y = mx+b) of a line based on two coordinates.
- Slope between two points: This provides the slope between two coordinates.
- Linear Equation: This computes the range (y) of a linear equation (y = mx +b) and includes a graphing function.
- Probability between z SCORES: This computes the area under the Normal Distribution curve between two z SCOREs which equates to the probability of an event in that range.
- Stats Calc: College level statistics calculator with a bundle including most of the functions in this list.
- Count: This computes the number (n) of observations in a set of numbers.
- Minimum: This computes the minimum (min) value in a set of numbers.
- Maximum: This computes the maximum (max) value in a set of numbers.
- Numeric Sort: This sorts (ascending or descending) a set of comma separated numerical observations.
- Random Sample (k items): The provides a random subset of a specified size (k) in a set of comma separated numerical observations.
- Random Real Number in Range: The provides a random real number between two specified real numbers (upper and lower bounds).
- Radom Integer: The provides a random integer between two specified integers (upper and lower bounds).
- Frequency Distribution: This provides a frequency distribution table for a comma separated set of numbers with a specified number of frequency bins between a lower and upper data range.
- Sum (Σx): This is computes the sum of the values in a set.
- Sum of Squares (Σx²): This computes the sum of the squared values in a set.
- Sum Squared (Σx)²: This computes the square of the summed values in a set.
- Mean (μ): This computes is the mean (average) of values in a set.
- Median: This identifies the middle ordered value in a set of numbers.
- Statistical Mode: This identifies the most recurring observation in a set of numbers.
- Mid Point: This is identifies the mid point of the observation range in a set of numbers.
- Range: This is computes the difference between the max and the min values in a set of number.
- Population Variance (σ2): This computes the variance, a metric regarding the spread of values, for a population set of numeric values.
- Population Standard Deviation (σ): This computes the standard deviation for a population set of numeric values.
- Sample Variance (s2) : This computes the variance, a metric regarding the spread of values, for a sample set of numeric values within a greater population.
- Sample Standard Deviation (s): This computes the standard deviation for a sample set of numeric values within a greater population.
- z SCORE Formula: This computes the z SCORE for a value base on the mean and standard deviation.
- z SCORE: This computes the z SCORE for a value (Raw Score) based on a set of values, and whether that set is sample or population.
- Percentile: This computes the percentile of a value (y) in a set (X) of values.
- Standard Deviation of Mean (SDOM): This computes the standard deviation of mean, sometimes also known as the standard error of the mean (SEM), useful to helps quantify the uncertainty in the estimate of the mean.
- Percent Relative Standard Deviation (%RSD): This computes the percent relative standard deviation, also known as the coefficient of variation (CV). The %RSD is a measure of the dispersion of a probability distribution.
