Answer:
7.62
Step-by-step explanation:
We can draw another point at (-3, -4) named C to get a right-angled triangle.
AC = 2 (by counting)
BC = 7 (by counting)
Using Pythagoras Theorem,
[tex]AC^{2} +BC^{2} =AB^{2}[/tex]
[tex]2^2+7^2=AB^2[/tex]
[tex]4+49=AB^2[/tex]
[tex]AB^2=58[/tex]
[tex]AB=\sqrt{58} = 7.62[/tex] (nearest hundredth)
