What is the least common multiple (lcm) of these monomials? 12a^2 b^6, 28a^4, 42ab^3

I guess 2 is the least common multiple

A line that has a 0 slope is a horizontal lineit is represented by y = a numberso a line with a zero slope WILL touch the y axisit will touch the y axis at y = 1

just so u know...it is a vertical line that does not touch the y axis

so ur answer is y = 1this line has no slope but it touches the y axis
