Answer:
Opt D. 5
Step-by-step explanation:
This is the distance between two points, which can be obtained with following equation.
[tex]d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}[/tex]
Where (x2,y2)=(7,-9) and (x1,y1)=(4,-5)
Therefore, if we develop a little with the following:
(7-4)^2=(3)^2=9
(-9+5)^2=(-4)^2=16
Evaluating that in the equation, we have: sqrt(16+9)= sqrt(25)=5
That is the distance between those points.
