Correct. The x-intercept of the line is the point (x,0) that lies on the line. Using the pattern described in the table, the slope of the line is -4, so the points (4,2) and (5,-2) are also on the line. Since the slope of the line is -4, we know that the point (4.5,0) is also on the line, showing that the x-intercept is (4.5,0).
