The segment is a straight line that connects the two points C and D. We want to determine the distance between C and D. Looking at the given points, the x cordinates are 3 and 7. The y coordinates are 6 and - 3.
The first step is to determine the distance between the x coordinate. We can subtract the higher value from the lower value but we must take the absolute value. Therefore, the distance between the x coordinate is 3 - 7 = - 4. The absolute value is 4
The distance between the y coordinate would be 6 - - 3 = 9. The absolute value is 9
The next step is to find the square root of the sum of both distances. It becomes
The length of the segment is 9.85
