Question

The lines 2x - 3y = 1 and 2x + 3y = 2 are intersecting.
True
False

Answer 1

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.
True
False

Answer 2

put each into form y = (slope) x + (y-intercept)

y = m x + b

lines with different slopes intersect, those with the same slope do not [though they could be identical if b is also the same].
