Treat the data as ordered pairs. From the table, write the goals as x - coordinate and the assists as y - coordinate.
\Plot the ordered pairs as points in a coordinate plane.
\The scatter plot shows a positive correlation between x and y. This means that as the x - values increased, the y - value tended to increase, so you can fit a line to the data.
\\
Draw a line that appears to fit the points in the scatter plot closely.
