How to Find the Intersection of Two Equations?

Basic algebra often requires you to find the intersection of two lines, of the form ax + by = c and dx + ey = f. Accomplish this by solving for either y or x in both equations, then setting the equ... Read More »

How to Find the Intersection of Two Parabolas?

A parabola is a curve formed by a set of points that are equidistant from a line and a given point. A parabola can be written as y = ax^2 + bx + c, where a is not equal to 0. Two parabolas can int... Read More »

How to Algebraically Find the Intersection of Two Lines?

When straight lines intersect on a 2-dimensional graph, they meet at only 1 point, which can be described by a single set of x- and y-coordinates. Because both lines pass through that point, you kn... Read More »

How to Find the Point of Intersection of Graphs F(X)=G(X)?

Finding points of intersection of two functions is a common exercise in Algebra I and II, since it demonstrates the usefulness of solving equations. Find the intersection of two functions f(x) and ... Read More »
