Find the distance, c, between (0,0) and (-4,-3) on the coordinate plane. Round to the nearest tenth if necessary.

taurus [48]

Answer:

Step-by-step explanation:

To solve the equation you'll use the distance formula:

$\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Substitute the equation with (0,0) being $x_{1}$ , $y_{1}$ and (-4,-3) $x_{2},y_{2}$

$\sqrt{\left(0+4\right)^{2}+\left(-3+0\right)^{2}}$

if you solve this you'll get 5
