The coordinates of (-6, 4) satisfy the equation y=+6 because (-6, 4) [
If (-6,4) satisfies the equations of two lines, (-6, 4) is
This means that if two lines
so the lines will
at (-6, 4), then (-6, 4) is the
This means that if you substitute -6 for x and 4 for y in the equations, both equations will be
at (-6, 4).
