Describe the strength and direction of the relationship shown in the following scatter plot

Some students took a mathematics test and a science test. Table given below shows the marks in mathematics test and science test

\begin{array}{|l|l|l|l|l|l|l|l|l|}
\hline \text { maths } & 10 & 20 & 30 & 35 & 40 & 50 & 55 & 52 \\
\hline \text { science } & 15 & 25 & 20 & 30 & 35 & 40 & 50 & 55 \\
\hline
\end{array}
