What is the slope of the line with points (6, -4) and (2, 8) ?

  1. -1/2

  2. -2

  3. 1/2

  4. 2

The correct answer is: -2

To find the slope of a line, we use the formula m = (y2 - y1) / (x2 - x1). In this case, (x1, y1) = (6, -4) and (x2, y2) = (2, 8). Plugging in these values, we get m = (8 - (-4)) / (2 - 6) = 12 / -4 = -3. Therefore, the slope of the line is -3. Option A is incorrect because it is the slope for the line passing through the points (6, 4) and (2, 8) (note the positive y-values). Option C is also incorrect because it is the reciprocal of the correct slope (-2/1). Option D is incorrect because it is the slope for the line passing through the points (6
