distance
Explanation:
Start by labelling each coordinate.
#(x_1,y_1)=(color(red)(-2),color(blue)3)#
#(x_2,y_2)=(color(darkorange)(-2),color(purple)(-7))#
Using the distance formula,
#d=sqrt((x_2-x_1)^2+(y_2-y_1)^2 )#
substitute the variables into the formula to find the distance between the two coordinates.
Thus,
#d=sqrt((color(darkorange)(-2)-(color(red)(-2)))^2+(color(purple)(-7)-color(blue)3)^2 )#
#d=sqrt((-2+2)^2+(-10)^2)#
#d=sqrt(0+100)#
#d=color(green)(|bar(ul(color(white)(a/a)color(black)(10)color(white)(a/a)|)))#
