Work Step by Step
We imagine a straight line through all of the data points, and we see that this line would intersect the y-axis at y=3. Of the answers given, only G and I have a y-intercept of 3. (They are in the form y=mx+b, where b is the y-intercept). I has a slope of 3, which is greater than the slope of the line through the points, so G is the correct answer.
