Question

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

Answer 1

d = √(x²~x¹)² + (y²-y1)²

Explanation:

√(1--3)² + (7-2)²

the square root covers everything

then put this answer on the calculator

Answer 2

`√(41)`

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=√((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=√((-3-1)^2+(2-7)^2)`

->
`D=√((-4)^2+(-5)^2)`

->
`D=√(16+25)`

->
`D=√(41)`
