We are given the following vectors:


\begin{gathered} v_1=(2,4) \\ v_2=(-1,5) \end{gathered}

We are asked to determine the dot product of the vectors. The dot product is defined as the sum of the product of each corresponding coordinate of the vectors, that is:


v_1\cdot v_2=(2)(-1)+(4)(5)

Solving the product:


v_1\cdot v_2=-2+20

Solving the addition:


v_1\cdot v_2=18
