Which point on the number line represents the zero of the polynomial \(s(x)=5x-10\)?

Answer and explanation

Correct answer: 2

The zero of a polynomial is the value of \(x\) for which the polynomial becomes zero. Thus, \(5x-10=0\), so \(5x=10\) and \(x=2\). Therefore, the correct point on the number line is 2. The value 5 is only the coefficient of \(x\), not the zero. In an exam, first set the polynomial equal to zero to find its zero.
