Question

Equation of the line passing
throgn (oo) and ​

Answer 1

Answer:

If b isn't zero I can get (1,-a/b,0), which has the slope of the line as its second coordinate. Excellent. This just leaves the line at infinity as a line. We already know that all the points on the line at infinity have their third coordinate equal to zero, so the equation of the line at infinity ought to be w=0.
