Answer

Steps are included the distance formula is the square root of the equation (x2-x1)^2+(y2-y1)^2

$\sqrt{ \left( 2 - -4\right)^2 + \left( 3 - -5\right)^2}\\ \sqrt{ \left( 2 + + 0\right)^2 + \left( 3 + 5\right)^2}\\\sqrt{\left( 6\right)^2 + \left( 8\right)^2}\\\sqrt{ 36 + 64 }\\ \sqrt{ 100 } \approx 10$
