This video describes why the method for finding the intercepts works, then demonstrates finding the intercepts for an example equation and graphing its line.


This demonstrates how to find these values for a quadratic equation of the form y = ax^2 + bx + c.


This gives a graph of a parabola which is the graph of a quadratic equation or function. The demonstration first includes classifying it as a parabola that is opening downward or upward. Then it…


Looks at the three types of graphs that can occur with a system of two linear equaltions in two variables.


Just showiing how to locate and write down the xintercepts and yintecepts when looking at a graph


Shows how to substitute zero for y to find the xintercept and zero for x to find the yintercept.


Finding the points where a particular graph crosses each axis on the xy coordinate plane.
