What that means is that if you can use one pair of numbers $x$ and $y$ that lie on the line you can find the value of $m.$ In your question (1, 3) lies on the line so it must satisfy the equation, that is $3 = m \times 1.$ Solve this equation for $m.$ with this value of $m$ does (2, 6) also lie on the line?
