Answer: 7 units
Step-by-step explanation: In this problem, the given numbers -3 and 4 represent the coordinates of the endpoints of a segment and we are asked to find the length of the segment.
To find the length of a segment, we take the greater endpoint coordinate minus the lesser endpoint coordinate.
In this case, the greater endpoint coordinate is 4 and the lesser endpoint coordinate is -3.
So, we have 4 - (-3) which can also be thought of as 4 + 3 which equals 7.
Therefore, the length of this segment is 7 units.
