Explanation:
#"to calculate the distance (d) use the "color(blue)"distance formula"#
#color(red)(bar(ul(|color(white)(2/2)color(black)(d=sqrt((x_2-x_1)^2+(y_2-y_1)^2))color(white)(2/2)|)))#
where# (x_1,y_1),(x_2,y_2)" are 2 coordinate points"#
#"the 2 points are " (x_1,y_1)=(3,-2),(x_2,y_2)=(2,-4)#
#d=sqrt((2-3)^2+(-4+2)^2)=sqrt(1+4)=sqrt5~~2.236#
