Question

The distance between point (-5, 7) and (-1,3) is : 2

a. 4√2. b. 9√2 c. 7√3. d. 6√2​

Answer 1

Given:

Points are :

(-5,7) and (-1,3).

To find :

• Distance between the points:

Solution:

• As we know that:

$\star \boxed { \blue{ \bold{ d = \sqrt{ ({x_2 - x_1)}^{2} + ( {y_2 - y_1)}^{2} } }}}$

Here,

• x1= -5 and y1= 7

• x2= -1 and y2= 3

$\implies \: d = \sqrt{( { - 1 - ( - 5))}^{2} + {(3 - 7)}^{2} } \\ \\ \implies \: d = \sqrt{ {(4)}^{2} + ({ - 4}^{2} ) } \\ \\ \implies \: d = \sqrt{16 + 16} \\ \\ \implies \: d = \sqrt{32} \\ \\ \implies \: d = 4 \sqrt{2}$

Hence , Option A is correct .
