Review Learning Goals:  I can find the point of intersection between two lines algebraically  I can expand expressions  I can use trigonometry to find sides and angles on triangles

Review Point of Intersection When we find the point of intersection between two lines we are finding the solution to the linear system. At the point where the two lines intersect they have the same “x” and corresponding “y” value.

Review Point of Intersection What ways do you know to find the POI or the solution to a linear system?
