Based on the scatter plot below, which is a better prediction for y when x = 5?

You can use a trend line to make predictions from a scatter plot.

Draw the line that best fits the data.

Find the point on the line where x = 5. Locate 5 on the x-axis, then move up until you intersect the line.

Now move left until you intersect the y-axis.

You intersect the y-axis at around 0.

So, when x = 5, the better prediction for y is 0.
