Find the slope of (0, 4), (− 5, 2)

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

One integer is 8 times another. if the product is 72, then find the integers

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
