The slope of a line is represented by the equation (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are the coordinate points of the line. In this case, (2, 7) and (4, 3) are the two given points.

When solving for slope, we get (3-7)/(4-2) = -4/2 = -2.

Therefore, the slope of the line is -2, making option D (D -1) the correct answer.

The other options (A: 3, B: 1, C: -3) do not accurately represent the slope of the given line, as they do not match the obtained value of -2.
