If the question is 'what symbol is used for this concept then I think that is offtopic here, it is a question about mathematical convention, not TeX. A question about how to generate a specific symbol in (La)TeX on the other hand, would be on topic. Feb 19, 2013 The xintercept isn't part of the equation because it is the value of x when y0; in other words, x acts as the dependent variable and y the independent variable. That isn't compatible with an equation for graphing, where you use y as the dependent variable.
Why is the yintercept called b? Filed Under: Algebra; This post has 10 comments join the discussion! Ive been teaching and tutoring the slope intercept form of the equation of a line for 25 years. Slope Intecept Form Calculator Find the slope intercept form of a line given two points, a function or the intercept stepbystep The y intercept is 2 for the red line, 0 for the green line, and 2 for the blue line. In the equation for a straight line, shown below, the y intercept is one of the key parameters: y mx b.
where m is Chapter 8: Linear Regression. STUDY. PLAY. the yintercept. What is the model for the least squares line built from? 1. the correlation How do you write this last equation using symbols?
e y y hat. When we want to know how How can the answer be improved? Because at the yintercept the place where the line crosses the yaxis 'x' is zero. Y intercept symbol you take the equation for the line and make 'x' zero, you'll find that [ y b.
So that means that 'b' is the yintercept. The Mathematical Symbols used in Statistics wayne. [email protected] edu [ updated: Saturday, April 19, 2008 pronunciation and vernacular for each symbol is included as well.
Symbol Concept Population Sample Number of yintercept (constant) b0 Regression slope b1 Alphabetical Statistical Symbols: Symbol a b Text Equivalent Meaning Y intercept of least square regression line Slope of least squares regression line b y intercept of a line. Defined here in Chapter 4. (Some statistics books use b 0. ) BD or BPD binomial probability distribution. Defined here in Chapter 6. CI confidence interval. Defined here in Chapter 9. CLT Central Limit Theorem.

Alphabetical Statistical Symbols: Symbol Text Equivalent Meaning Formula Link to Glossary (if appropriate) a Y intercept of least square regression line a y bx, for line y a bx Regression: y on x b Slope of least squares regression line b In analytic geometry, using the common convention Y intercept symbol the horizontal axis represents a variable x and the vertical axis represents a variable y, a yintercept or vertical intercept is a point where the graph of a function or relation intersects the yaxis of the coordinate system.
As such, these points satisfy x 0. Oct 15, 2003 In the slopeintercept formula y mx b Why is the letter" b" used to represent the yintercept? It may be helpful to know that in class we established the reason for" m" representing the slope of the line.
We're going to analyze various situations to understand what the slope and yintercept represent. You will watch videos to further your understanding.
