Question

Find the distance between the points (3, 8) and (-1, 9).

Answer 1

distence between points (x1,y1) and (x2,y2)\[d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\]

Answer 2

First use distance formula:sqrt((x2-x1)^2+(y2-y1)^2)
Here,x1=3,x2=-1,y1=8, and y2=9
sqrt((-1-3)^2+(9-8)^2)
sqrt((-4)^2+(1)^2)
sqrt(16+1)
sqrt(17)
