Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. X and Y intercepts are part of the basis for solving and graphing liner equations. The X-intercept is the point at which the equations line will cross the X axis, and the Y intercept is the point at which the line crosses the Y axis. Finding both of these points will allow you to locate any point on the line. This article describes the formula syntax and usage of the INTERCEPT function in Microsoft Excel. Description. Calculates the point at which a line will intersect the y-axis by using existing x-values and y-values. The intercept point is based on a best-fit regression line plotted through the known x-values and known y-values. You can solve for x by using the square root principle or quadratic formula (if straight lines are created functions whose highest power of is 1, and here most convenient form to use find intercepts 25 apr 2017 equations parabolas that intercept y axes depending on their constants. X intercepts of a quadratic function varsity tutors. Free functions intercepts calculator - find functions axes intercepts step-by-step Finding the x- and y-intercepts of an equation are important skills you'll need in math and the sciences. For some problems, this may be more complicated; fortunately, for linear equations it just couldn't be simpler. A linear equation will only ever have, at most, one x-intercept and one y-intercept. Math explained in easy language, plus puzzles, games, quizzes, worksheets and a forum. For K-12 kids, teachers and parents. how to find X-intercept. Learn more about x intercept. Hello I am plotting X vs Y and would like to know what is the value of X when Y is equal to zero. To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y. If you don't know the slope, calculate it by dividing the rise of the line by the run.
