whats negative -7 subtracted by 4?

AZ · Answer

$ \Large\text{Distance} = \sqrt{ (\color{cyan}{x_2} -\color{red}{x_1})^2 + (\color{green}{y_2} - \color{orange}{y_1)}^2 } $

where you have two points
$\Large (\color{red}{x_1}, \color{orange}{y_1})$ and $\Large (\color{cyan}{x_2}, \color{green}{y_2})$

So your two points are

$(\color{red}{-7}, \color{orange}{5})$ and $(\color{cyan}{4}, \color{green}{-3})$

ok

^^^ is used to calculate the distance between two points
We need to subtract that x values together, square it, and add it on with the different squared y.

So, we have (-7,5) and (4,-3)

we do

(x2 - x1)^2, plug it in as 
(4-(-7))^2
^ is the first half

and then we have

(y2 - y1)^2 which is --
(-3-5)^2

Can you first simplify

$$(4-(-7))^2 + (-3-5)^2$$
