The slope between points C and D is 12/7 = 1.71
We know that the slope between two points with coordinates (x₁, y₁) and (x₂, y₂) is given by:
s = (y₂ - y₁)/(x₂ - x₁)
In this case, the coordinates of point C are (0, 0)
The coordinates of point D are (7, 12)
Then the slope on that interval is:
s = (12 - 0)/(7 - 0) = 1.71
