Question

Find the distance between each pair of points:
a(4,7) b(1,3)

Answer 1

I think you would do sqrt((x1-x2)^2+(y1+y2)^2)=distance. The ones and twos next to the x and y are supposed to be subscripts.

Answer 2

oh sorry sqrt((x1-x2)^2+(y1-y2)^2)=distance I accidentally wrote a plus btw the y's

Answer 3

\[\sqrt{(1-4)^2+(3-7)^2}\]
\[\sqrt{(-3)^2+(-4)^2}\]
\[\sqrt{9+16}\]
\[\sqrt{25}\]
