Final answer:
To find the coordinate of point E that is 1/4 of the way from C to D, subtract 6 from 14 to get a distance of 20, then multiply it by 1/4 to get 5, and add 5 to -6 to get the coordinate of E which is -1.
Step-by-step explanation:
To find the coordinate of E, which is 1/4 of the way from C to D, we need to find 1/4 of the distance between -6 and 14. First, we find the distance between C and D: 14 - (-6) = 20. Then, we find 1/4 of this distance: (1/4) * 20 = 5. Finally, we add this to the coordinate of C to find the coordinate of E: -6 + 5 = -1.
