Question 34

What is the distance between the points (11,-5) and (-1,0)?

Solution

Distance between two points $$(x_1 , y_1)$$ and $$(x_2 , y_2)$$ = $$\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}$$

Now, distance between points (11,-5) and (-1,0)

= $$\sqrt{(-1 - 11)^2 + (0 + 5)^2} = \sqrt{(-12)^2 + (5)^2}$$

= $$\sqrt{144 + 25} = \sqrt{169}$$

= $$13$$ units

=> Ans - (C)
