# slope formula to find y intercept

Line and Slope Formulas. Finding the Slope.Just remember to re-write any given equations into the proper slope- intercept form and keep in mind your rules for finding slopes (and your rules for parallel or perpendicular lines). Once youve found the linear regression equation, all thats required is a little algebra to find the y-intercept (or the slope). Note: You may also see the regression slope intercept formula written as a y bx. Lets find how.So, it is just the slope formula in a different way!Slope (Gradient) of a Straight Line Y Intercept of a Straight Line Test Yourself Explore the Straight Line Graph Straight Line Graph Calculator Graph Index. So lets use the Point-Slope Formula to find the equation of the line.which is now in form where the slope is and the y-intercept is. Notice if we graph the equation and plot the point ( , ), we get (note: if you need help with graphing, check out this solver ). You found the slope (m) to be . Insert as m in the slope intercept formula.Algebraically Finding the y- intercept with the Slope and another Point. The online Slope Intercept Form Calculator is used to help you find the slope intercept form for the equation of the straight line which passes through two points. It also calculates the slope and the y-intercept of the line. Pick any two points to find the slope. Lets use points A and B. Starting at point A counting three straight down for the rise.What form is that in? It is in y mx b In this formula m is the slope of the line and b is equal to the y intercept. The y-intercept is not given so we can solve for it by using a NEW formula called POINT-SLOPE FORMULA!Points (4, -2) and (1, 4) We must find the slope! y - y1 m(x x1). Formulas. Slope formulaThe given equation of a line and the relationship to find the slope. (Parallel use the same slope, perpendicular use the opposite-reciprocal slope).

The slope intercept form calculator tells you how to find the equation of a line for any given two points that this line passes through. It will help you find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas. Your slope, in this case, is equal to (-3)/(3), or -1. Plug the slope, along with either of your points, into the formula y mx b, in which b is the y-intercept.(2017, April 25). How to Find Slope Y-Intercept in Economics. Using any two points on a line, you can calculate its slope using this formula.This is another way to find the y-intercept, if you know the equation, the y-intercept is the solution to the equation when x 0. Formula Slope Formula: m y2 y1.

Uses and Comments Use: To find the slope of a line containing two points. Uses: 1) Graphing with y-intercept and slope rise. Again the concept intercept form includes x and y intercept. Finding slope is done with the help of the point slope formula. Thus all these topics are interrelated.
