Terminology
- point of intersection
- common point
- ordered pair
- graph scale
- parallel lines
- coincident lines
Task goals
- Locate where two straight lines cross and read the intersection as an ordered pair, x-coordinate first.
- Read intersections in all four quadrants and on either coordinate axis.
- Use finer graph scales to estimate half-unit and decimal intersection coordinates.
- Explain when a displayed graph has one intersection, no intersection, or coincident lines with infinitely many common points.

You are here
Finding point of intersection of two lines
Know
In the equation of a line y = mx + c, m and c represent constants (they are unchanging), y and x can vary, and all the values of x and y that satisfy the equation create an infinite number of points that form the line.
