Answer 1

Hi Jaida,

Assuming the line you drew is the regression line and assuming that the model follows that line, you can see that when x is about 30, y is about 90. Note: don't look at the dots. Those are actual, not predicted, data points. Closest approximation without an actual regression equation is y^=91.
