Answer:
[tex]\sqrt{120}[/tex] or [tex]2\sqrt{30}[/tex]
Step-by-step explanation:
Using the pythagorean theorem, if you find the lateral and vertical distance between the two points you can find the overall distance. The lateral distance between the two is 2-(-1)=3 units, while the vertical distance is 7-(-4)=11. Plugging this into the formula, you get [tex]\sqrt{3^2+11^2}=\sqrt{120}=2\sqrt{30}[/tex]. Hope this helps!
