What is an equation of the line that passes through the point ( 4 , 6 ) and has a slope of -3

When are two distinct non vertical lines parallel

What is the multiple zero and multiplicity of f(x) = (x ? 3)(x ? 3)(x + 5)? multiple zero is 3; multiplicity is 2 multiple zero is 5; multiplicity is 1 multiple zero is ? 5; multiplicity is 1 multiple zero is ? 3; multiplicity is 2

Is this a polynomial function? i need to know asap
