Question

What is the distance between (2, -1) and (-1, -5) on the coordinate plane? 7 units 6 units 5 units 4 units

Answer 1

You can use the distance formula: 
$\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Plug in the given coordinates: 
$\sqrt{(-5-2)^2 + (-1+1)^2}$

$\sqrt{(7)^2 + (0)^2}$

$\sqrt{49+0}$


$\sqrt{49}=7$

Final answer : 7units
