Identify the ordered pair that represents the vector from a(-8,-1) to b(-5,3) and the magnitude of vector ab.

In order to find the vector that points from A to B we need to subtract each component of A from the corresponding component of B, according to the formula: v(a→b)=(b1−a1,b2−a2) In this case we have : v(a→b)=(−5−(−8),3−(−1)) v(a→b)=(3,4)

To find the magnitude we use the formula: ||v|=  √(v1^2)+(v1^2)

So:
||v|= √(32)+(42) ||v|=  √9+16 ||v|= √25  ||v|= 5

The answer is: m > -4
