Question 158938
An infinite number of lines can intersect a point.
y=x (red line)
y=2x (green line)
{{{ graph( 300, 200, -6, 5, -10, 10, x, 2x) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x and 2x).
y=5x red line (red line)
3y=x 
y=x/3 (green line)
{{{ graph( 300, 200, -6, 5, -10, 10, 5x, x/3) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 5x and x/3).
