This lesson demonstrates graphing two lines on a coordinate plane and determining the point where two lines intersect. It is 3 of 5 in the series titled "Finding Intersections."

Find the treasure hidden at an intersection in the city. Use the clues. Read the instructions then scroll to the bottom and click "hide the treasure".

Solve equations and find zeroes of functions using the TI-83 in this lesson. Keystroke instructions and calculator screenprints are included to help students with the activity.

A collection of activities where students investigate linear systems. Activities explore their features, points that are common to a system of two linear equations, ways to express a solution, using a system to make predictions, finding...

This InterMath site gives a description of the incenter of a triangle along with a visual representation. Be sure to follow the links to related terms, everyday examples, challenging problems, and the interactive check point involving...

In Spanish. This math game is for two players. The goal is to join the green points on the side of the square with a straight line and get the highest number of intersections between the drawn lines.

Solve a number riddle by finding the point of intersection for two lines. This video focuses on finding the solution for a system of equations, they are represented as an algebraic expression and a set of linear equations that are...

Tracking equipment is used to help ship navigators traveling in dense fog determine if they are in danger of colliding with other ships that may be in the area. For this activity, we are going to assume two ships are traveling along...

Students will submit equations in vertex form that will match the roller coaster using activity center. They will also find the intersection point of two roller coasters.

A pan balance helps students visualize what value for x will make two expressions equivalent. The computer applet graphs the lines and shows the intersection point.

This animation depicts the path of light to each person's eye. Different people are sighting in different directions; yet each person is sighting at the same image location. In this animation the image location is the intersection point...

Students are required to solve a system of equations in this task which will demonstrate their understanding of the correspondence between intersection points of the two graphs and solutions of the system. Aligns with A-REI.C.7.

This site from InterMath gives a description of the orthocenter of a triangle along with a visual representation. Be sure to follow the links to related terms, everyday examples, challenging problems, more information, and the...

In this activity, students' will collect and analyze motion data in order to determine the solution to a linear system of equations. They graph two motions on a common axis and find their intersection.

Goes over the equation of a circle, parametric equations of a circle, intersection of circle and line, tangent line in a point of a circle, etc.

Find the gradient, equations and intersections of medians, altitudes and perpendicular bisectors using our knowledge of the mid-point as well as parallel and perpendicular lines.

Students are introduced to quadratic functions. The tutorial explores the equation of a quadratic function, intercepts, graphing, and points of intersection. The activity consists of examples with detailed solutions.

When a line intersects a circle in exactly one point the line is said to be tangent to the circle or a tangent of the circle.

In the center of downtown Atlanta, a handful of streets intersect, forming what locals know as Five Points. Today, a park, a university, high-rise buildings and throngs of motorists and pedestrians make this a bustling area, belying its...

Not only does this site show what the slope-intercept form is, but it helps you find the slope and the intercept of a line. There is also additional information on parallel lines, parametric form, and the distance between two points.

In this lesson we are going to explore the most fundamental calculation a ray tracer performs: ray object intersection. It also lists information you need to know before you start this lesson.

Jackie and Matt are looking at the same object along two different lines, in this video segment from Cyberchase.

Covers the basic definitions involved in systems of linear equations.
