How to Find the Intersection of Two Equations?

Answer 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 Number of Points of Intersection Given Two Linear Equations?

Linear equations are exactly what they sound like: lines. With two linear equations in a plane, unless they are parallel they will have one intersection point. To find this intersection point, whic... Read More »

How to Find the Intersection of Two Functions?

A function on a graph displays an algebraic equation visually. A line, for instance, that runs parallel to the x-axis and crosses the y-axis at the "5" mark represents the equation "y = 5." A line ... 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 »
