Show that the line \(y = 2x + 1\) intersects the circle \({x^2} + {y^2} - 6x - 7y + 9 = 0\) and determine the points of intersection. Therefore the line \(2x + 1 ...

The three lines in this image are intersecting. They intersect at a common point. This is called the point of intersection. In this parallelogram, there are two pairs of parallel lines.
