Virtual Nerds patent-pending tutorial system provides in-context information hints and links to supporting tutorials synchronized with videos each 3 to 7 minutes long. In this tutorial youll see how to find the x-intercept and the y-intercept for a given linear equation.

18 12 30. Ya x-p x-q is the general form for intercept form In intercept form p and q are the x-intercepts So in our equation the x-intercepts are -3 and 1 yax 2 bxc is the general form for standard form. To find the y-intercept plug 0 in for x and solve for y.

Therefore 43 is a solution to this problem. To find the y-intercept remove the x and solve for y. By reading our graph we see that if Emily bought 3 6 books she could buy 4 3 books.

The equation of a line in standard form is. In this non-linear system users are free to take whatever path through the material best serves their needs. For an organized list of my math videos please go to this website.

In this tutorial youll see how to find the x-intercept and the y-intercept for a given linear equation. These unique features make Virtual Nerd a viable alternative to private tutoring. Finding the x-intercepts means to find the values of x when a x 2 b x c 0.

In this video we learn how to find the x and y intercepts of a linear equation in two variables written in standard form. The X-Intercept Formula of a line Ax By C is The X-Intercept Formula of a line in the slope-intercept form y mx c is Where m is the slope of the line. To solve we say that x 2 x 6 0.

2 2Ax By C 2 2 where A is a positive integer and B C are integers the equation of a line in slope-intercept form is. This activity is meant to be a station where students discover the short cut to finding intercepts and slope when given an equation in standard form. After completing the task a.

This can somtimes be done using factorisation by inspection. C is the intercept of the line. To find the x-intercept of a given linear equation simply remove the y and solve for x.
