Question

Find the distance between the points E(1,7) and F(-3,2).​

Answer 1

Answer:

d = √(x²~x¹)² + (y²-y1)²

Step-by-step explanation:

√(1--3)² + (7-2)²

the square root covers everything

then put this answer on the calculator

Answer 2

Answer:

$\sqrt{41}$

Step-by-step explanation:

First of all this is too easy, if you are having problems with this then I highly recommend you to ask your teacher for help

Formula ->  $D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Identify which is x and which is y

-> E (1,7) F(-3,2)

    |$x_1$|$y_1$|    |$x_2$|$y_2$|

-> $D=\sqrt{(-3-1)^2+(2-7)^2}$

-> $D=\sqrt{(-4)^2+(-5)^2}$

-> $D=\sqrt{16+25}$

-> $D=\sqrt{41}$
