Here's the question again
How do I find all line through (6, 1) for which the product of x & y intercepts is 3?
Thanks again

The equation would have the form
(y+1) = m (x6),
where m is the slope. It can be rewritten
y = mx 6m 1
The y intercept is at y = 6m 1.
The x intercept is at x = 6 + 1/m
Require that (6m 1)*(6 + 1/m) = 3, and solve for m.
