Answer:
Point B would be at 5.
Explanation:
Given segment AC in which point A is at -3 and point C at 7, representing this on the number line shows that there are 10 points from A to C.
-3 -2 -1 0 1 2 3 4 5 6 7
A C
Since the segment AC is to be divided into a ratio 4:1, then moving from point A to B (at point 5) would be the required point. Therefore, point B that would divide segment AC in ratio 4:1 is at 5.
Thus, A is at -3, B is at 5, and C is at 7.
